摘要
教学督导对高校教学质量的提高起着保驾护航的作用,为了有效地发挥督导体系对高职院校教学质量的保障作用,应当健全教学督导工作制度,形成特色的高职高专督导运行模式,丰富并拓展教学督导工作的方法和内涵,构建科学合理的督导运行机制。
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.
