| 摘 要： | 本文利用数值计算方法,对圆管加热流动的热阻力和熵产进行了综合分析研究。以空气加热圆管为例,通过联立求解流体力学基本方程和熵产方程,获得了热阻力、熵产及其随加热量、管长而变化的关系。数值分析结果表明,加热流动中的热阻力与熵产二者之间存在着对应相关的关系。

| Abstract: | In this paper the thermal drag and entropy generation of a heated pipe flow are analysed by means of numerical computation. Through solving the fundamental equations of fluid mechanics and entropy generation, the thermal drag and entropy generation and their variations with the quantity of heat flux and length of pipe are obtained. The results of numerical analysis show that there exist relevant relations between the thermal drag and entropy generation of the heated flow. |
