热特性参数可变时抛物线型截面环肋传热的最优化研究

A Study on Heat Transfer of the Optimization in Circular Fins of Parabolic Profile with Variable Thermal Parameters

  • 摘要: 肋片传热的最优化的传统处理方法是当执行一定的传热任务时,具有最少的肋片材料消耗(投资).最少重量的冷却肋片是具有抛物线型的截面.本文应用不变嵌入原理研究了当热特性参数可变时抛物线型截面环肋传热的最优几何尺寸,同时还对两个主要的物理参数,即导热系数变化参数α和放热系数变化指数m对最优几何尺寸的影响进行研究.所得结果对工程设计具有现实指导意义.
