| 英文摘要 | Enhancing heat transfer efficiency is crucial in heat exchange equipment. Although previous studies have focused on developing micro/nano-structured surfaces, further exploration into how surface structure can improve heat transfer efficiency (H) by altering bubble dynamics is still needed. This study aimed to innovatively analyze the impact of titanium carbide (TiC) nanowire heights-specifically 4 mu m and 12 mu m-on boiling heat transfer performance. Conducted under varying heat flux (Q) (50-200 W/m2) and mass flux (G) (200-300 kg/m2 & sdot;s), our experiments assessed H, pressure drop (P), and local boiling curves. Using a high-speed camera, we observed complex periodic flow patterns on the 4 mu m nanowire surface, including elongated bubble formation, expansion, local dryout, and subsequent fluid rewetting. Results showed that the 12 mu m nanowire surface increased H by up to 19.84% in single-phase conditions, while the 4 mu m nanowire surface increased H by up to 27.9% in two-phase conditions. These findings highlight the significant role of nanowire length and arrangement in optimizing boiling heat transfer performance. This work lays a foundation for further investigations into diverse nanowire materials and configurations. |
