The flow direction is deflected due to the disturbance of the N-SS and W-SS bionic ribs (Fig. 7(a)), and the fluid of the boundary-flow zone is guided to flow into the core-flow zone, which results in the formation of multi-longitudinal swirls (Fig. 6) . This enhances the mixing of the cold fluid of the core-flow zone and the hot fluid of the near wall surface zone, strengthening the heat transfer rate in the bionic rib and its wake zone, and therefore increasing the heat transfer capacity of the tube wall (Fig. 7(b)). From the comparison of the N-SS and W-SS bionic ribs in Fig. 7(a), it can be seen that the W-SS bionic rib with split seam structure is designed by the shark skin bionic structure on the basis of the N-SS bionic rib. The split seam structure significantly enhances the guidance of the fluid flow in the boundary-flow zone, so that the fluid after flow through the split seam deviates from the mainstream direction to form the swirl, therefore, the W-SS bionic rib can better mix the fluid. As shown in Fig. 7(b), the heat transfer capacity of the tube wall surface is enhanced with the extension of the fluid flow path, which significantly improves the heat transfer capacity of the fluid, and the wall surface Nu of the W-SS enhanced tube is higher than that of the N-SS enhanced tube. The W-SS bionic ribs designed based on two bionic principles, fish scale, and shark skin, have the significant advantage in significantly improving the heat transfer capacity of the heat exchange tube.

The streamlines of the fluid flow through the bionic ribs and the wall surface Nu distribution of the enhanced tube are presented in Figure 7. The flow direction is altered due to the presence of N-SS and W-SS bionic ribs, as shown in Figure 7(a). The disturbance caused by these bionic ribs guides the fluid from the boundary-flow zone into the core-flow zone, resulting in the formation of multiple longitudinal swirls, as depicted in Figure 6. This intricate flow pattern enhances the mixing of the cold fluid from the core-flow zone with the hot fluid from the near wall surface zone. Consequently, it enhances the heat transfer rate in the bionic ribs and their wake zone, leading to an increase in the heat transfer capacity of the tube wall, as shown in Figure 7(b). 

A comparison between the N-SS and W-SS bionic ribs in Figure 7(a) reveals that the W-SS bionic rib, which incorporates a split seam structure based on the shark skin bionic structure of the N-SS bionic rib, significantly improves the guidance of fluid flow in the boundary-flow zone. As a result, the fluid flow after passing through the split seam deviates from the mainstream direction and forms swirls. Consequently, the W-SS bionic rib achieves better fluid mixing. Figure 7(b) demonstrates that the heat transfer capacity of the tube wall surface is enhanced as the fluid flow path extends, thereby significantly improving the overall heat transfer capacity of the fluid. The wall surface Nu of the W-SS enhanced tube is found to be higher than that of the N-SS enhanced tube. The W-SS bionic ribs, designed based on the bionic principles of fish scale and shark skin, show a significant advantage in enhancing the heat transfer capacity of the heat exchange tube.

Fig. 8 shows the effect of the bionic rib on the flow behavior by visualizing the vortex zone based on the Q-criterion [35] (Q=3000). The swirl structure is mainly generated in the vicinity of the bionic rib and its wake zone. This indicates that the bionic rib significantly influences the fluid flow behaviors, and promotes the formation and development of multi-longitudinal swirls. The W-SS bionic rib is more favorable to the formation of the longitudinal swirls than the N-SS bionic rib under the same working conditions, and thus the fluid is more fully mixed between the core and boundary-flow zone in the W-SS enhanced tube. Every time the fluid passes through the bionic rib, the intensity of the swirl is strengthened, which is manifested in the lengthening of the flow path in the core-flow zone of the swirl. From this, it can be seen that the pitch of the bionic ribs significantly influences the flow and heat transfer performance of the tube.

Figure 7 illustrates the streamlines near the bionic ribs and the distribution of the Nusselt number (Nu) on the enhanced tube wall surface under specific operating conditions (Re=15255, P=10mm, A=16mm2). Figure 7(a) shows the streamlines, while Figure 7(b) shows the distribution of Nu.

In Figure 8, the impact of the bionic rib on flow behavior is presented by visualizing the vortex zone using the Q-criterion [35] with a value of Q=3000. The swirl structure is primarily observed in the vicinity of the bionic rib and its wake zone. This observation suggests that the bionic rib has a considerable influence on fluid flow behavior and facilitates the formation and development of multiple longitudinal swirls. Comparatively, the W-SS bionic rib is more effective in generating longitudinal swirls than the N-SS bionic rib under the same operating conditions. As a result, the fluid is mixed more thoroughly between the core and boundary-flow zone in the W-SS enhanced tube. With each passage through the bionic rib, the swirl's intensity increases, leading to a lengthening of the flow path in the core-flow zone of the swirl. Consequently, it is apparent that the pitch of the bionic ribs significantly impacts the flow and heat transfer performance of the tube.

how to decipher and activate the ancient symbols of warding ?

Deciphering and activating ancient symbols of warding can be a complex and challenging task, as it typically involves deep knowledge of ancient cultures, symbolism, and sometimes even certain magical or spiritual practices. While I can provide you with a general direction, it's crucial to note that ancient symbols and their meanings vary across different cultures and civilizations. Here are some steps to get you started:

1. Research and Study: Begin by researching ancient cultures, their symbols, and their belief systems. Look for cultures known to use symbols for protective or warding purposes, such as ancient Egyptian, Norse, Celtic, or Native American cultures. Study their mythologies and symbols to gain a deeper understanding of their meanings.

2. Seek Expertise: If possible, consult with experts in the field, such as historians, archaeologists, anthropologists, or even practitioners of ancient mystical traditions. They may offer valuable insights into the interpretation, meaning, and uses of the symbols you are working with.

3. Symbol Catalogue: If you have discovered specific symbols and are unsure of their meaning, acquire or create a catalogue of ancient symbols. Organize and analyze them, noting any similarities or recurring themes.

4. Contextual Understanding: Understand the cultural, historical, and ritualistic context behind the symbols. Symbols often gain meaning in how they are used or combined with other elements within a specific belief system or framework.

5. Meditate and Connect: Develop a personal connection to the symbols you wish to decipher and activate. Meditate on them, observe their intricate details, and reflect on what they signify to you personally. This process can help you develop a more intuitive understanding of the symbols' potential purposes.

6. Experimentation and Ritual: Once you have a basic understanding of the symbols, their meanings, and their intended purposes, you can experiment with activating them. This involves performing ritualistic practices associated with the symbols, such as drawing them, chanting specific incantations, or manifesting their energy through visualization and focused intention.

Remember that working with ancient symbols can involve various levels of spirituality and magical beliefs. Depending on your personal beliefs, you may need to adapt this process to align with your specific worldview and practices. It's essential to respect and honor the cultural origins of these symbols while being mindful of potential cultural appropriation.

From the figure, it can be seen that the TKE close to the boundary-flow zone is much higher than that in the core-flow zone, which is attributed to the longitudinal swirl generated by the fluid passing through the bionic ribs to enhance the fluid disturbance. Higher TKE contributes to the disruption of the temperature boundary layer and accelerates the convective heat transfer, which indicates that more kinetic energy is consumed in the main flow direction and more pump power is required to maintain the fluid flow. The TKE of the W-SS enhanced tube is significantly higher than that of the N-SS enhanced tube, which indicates that the boundary-flow zone of the W-SS enhanced tube mixes more adequately with the core-flow zone, thus accelerating the convective heat transfer between the tube and the fluid. This is also the reason why the wall surface Nu of the W-SS enhanced tube is higher than that of the N-SS enhanced tube (Fig. 7(b)) and the temperature distribution is more uniform in the W-SS enhanced tube (Fig. 6). Therefore, The TKE enhancement in the enhanced tube is caused by multi-longitudinal swirls induced by the bionic ribs, and the increase in heat transfer capacity is directly related to the TKE enhancement. The above indicates that the increase of the TKE in the W-SS enhanced tube originates from the split seam structure of the shark skin bionic design.

Figure 9 illustrates the distribution of turbulent kinetic energy (TKE) at the axial section of the test section. The TKE near the boundary-flow zone is considerably higher than that in the core-flow zone, owing to the longitudinal swirl generated by the fluid passing through the bionic ribs, which enhances fluid disturbance. The elevated TKE disrupts the temperature boundary layer and accelerates convective heat transfer, implying that more kinetic energy is consumed in the main flow direction, necessitating increased pump power to maintain fluid flow. The TKE of the W-SS enhanced tube surpasses that of the N-SS enhanced tube, indicating that the boundary-flow zone of the W-SS enhanced tube mixes more thoroughly with the core-flow zone, thus enhancing convective heat transfer between the tube and the fluid. Consequently, the wall surface Nu of the W-SS enhanced tube is higher than that of the N-SS enhanced tube (Fig. 7(b)), and the temperature distribution is more uniform (Fig. 6). Therefore, the TKE enhancement in the enhanced tube is attributed to the multi-longitudinal swirls induced by the bionic ribs, and the increase in heat transfer capacity is directly linked to the TKE enhancement. Thus, the increase in TKE in the W-SS enhanced tube originates from the split seam structure of the shark skin bionic design.

使下列文字符合学术表达方式      Fig. 10. Comparisons of the thermal performance with the N-SS and W-SS enhanced tube (P=10mm, A=16mm2): (a) Nu; (b) Nu/Nu0
Fig. 11 compares the flow performance of the W-SS and N-SS enhanced tube. f and f/f0 increased with the increase of Re, and the variation of f/f0 ranged from 1.87 to 4.16. Both enhanced tubes increased the flow resistance, mainly due to the bionic ribs inducing longitudinal swirl in the fluid (Fig. 6), and the flow separation and confluence of the swirl consume the mainstream kinetic energy, thus increasing the flow resistance. f and f/f0 of the W-SS enhanced tube are higher than that of the N-SS enhanced tube, and the split seam structure brings more intense disturbance and higher TKE to the fluid in the tube (Fig. 9). Therefore, the improvement of heat transfer capacity of the enhanced tube often comes at the cost of flow resistance loss, and the heat transfer capacity and flow resistance of the W-SS enhanced tube are both higher than those of the N-SS enhanced tube.

Figure 10 displays a comparison of the thermal performance between the N-SS and W-SS enhanced tubes. The dimensions used in the study were P=10mm and A=16mm^2. Two parameters are presented: (a) Nu (Nusselt number) and (b) Nu/Nu0 (Nusselt number ratio).

Figure 11 illustrates the flow performance of the W-SS and N-SS enhanced tube. The parameters f (flow factor) and f/f0 (normalized flow factor) were analyzed with respect to the Reynolds number (Re). It was observed that both f and f/f0 increased as Re increased, with f/f0 ranging from 1.87 to 4.16.

Both enhanced tubes exhibited increased flow resistance, which can be attributed to the bionic ribs inducing longitudinal swirl in the fluid (as shown in Figure 6). The flow separation and confluence of the swirl resulted in the consumption of mainstream kinetic energy, ultimately leading to higher flow resistance. The W-SS enhanced tube exhibited higher values of f and f/f0 compared to the N-SS enhanced tube. This can be attributed to the split seam structure of the W-SS tube, which induced more intense disturbance and higher turbulent kinetic energy (TKE) within the fluid (as depicted in Figure 9).

Hence, it is important to note that the enhancement in heat transfer capacity often comes at the expense of flow resistance loss. In this case, both the heat transfer capacity and flow resistance of the W-SS enhanced tube were superior to those of the N-SS enhanced tube.
