变热特性参数条件下环形肋片非稳态传热研究

A Study on the Unsteady Heat Transfer of a Circular Finunder Variable Thermal Characteristic Parameters

研究在变热特性参数条件下，根部温度作周期性变化时环肋的传热规律．应用差分预测－校正格式的数值计算方法，分析了肋片的温度分布，热流量和肋效率受各种因素的影响状况．

A study is made on the heat transfer of a circular fin under variable thermal characteristic parameter and periodic change of finbase temperature. By applying difference forecast-correction scheme as themethod of numerical calculation,an analysis is made on the influence of various factors on temperature distribution,heat now and efficiency of the fin.
