在复杂边值条件下非稳态肋片传热的最优化（Ⅲ）

Optimization of Unsteady Heat Transfer of a Fin under Complex Boundary Value Conditions (Ⅲ)

研究在辐射和对流同时作用下肋根温度作周期性变化时矩形助片的传热特性．分析肋片的热流密度和肋片有效度与各种热特性参数的变化规律．

The heat transfer performance of a rectangular fin during periodic fin base temperature change is studied under simultaneous action of radiation and convection. In this third part, the regular pattern of the change of heat flow density and effective range of the fin with various thermal characteristic parameters is analyzed in detail.
