本文采用平行流数学模型,对理想回热器传热工况进行了分析。编制了回热器效率的计算程序,该程序是直接按回热器轴向长度及吹风周期,分别取一定数量的有限单元,这样可大为减少计算机迭代运算次数,而仍能保证所要求的精确度。
In this paper, parallel flow mathematical model is used to analyze the heat transfer condition of ideal regenerator. The calculation program of the regenerator efficiency is developed. The program is based on the axial length of the regenerator and the blowing cycle. A certain number of finite elements are taken respectively. This can greatly reduce the number of iterations of the computer and still guarantee the required Accuracy.
