摘要
介绍了一种新的求解辐射换热的方法—离散传播法,并编制了用该方法求解一维辐射换热问题的通用程序。用该程序对一维平行平板间的辐射换热问题进行了计算,并将结果与解析解进行了比较。结果表明,离散传播法是一种很好的求解辐射换热方法,值得进一步研究。
This paper introduces a new method, called the discrete transfer method to solve the radiative transfer equation. A program for the solution of one dimensional radiative heat transfer using this method is developed. The calculation of radiative transport in an absorbing planar medium is presented and the result is compared with the analytical exact one. It is apparent that the discrete transfer method is an effective method to solve radiative heat transfer and calls for further study and improvement.
