Abstract
The effect of pulse flow on the performance of heat exchange tube with built-in spring was investigated using software FLUENT. The temperature field and the pressure field under different pulse flow were obtained. Results indicate that the average export pressure shows the same vibration period with that of pulse flow and the fluctuation amplitude increases with the increment of the frequency of pulse flow; comparing with the case of steady flow, the thickness of velocity boundary layer decreases significantly and thus the heat transfer coefficient is enhanced greatly; the vibration amplitude of pulse flow has great effect on the heat transfer enhancement, while the frequency of pulse flow shows little influence on the heat transfer enhancement.关键词
