摘要
双自由边界Stefan问题的理论解在实用中很不方便,本文研究了热传导双移动边界问题,并提出了带有两条自由边界的Stefan问题的类Fourier型级数的近似求解方法。
The theoretical solutions of the Stefan problem with two free boun- daries are hardly applicable to engineering.In this paper,the two- moving-boundary problem of the-heat equation is studied and approximate solutions are obtained to the Stefan problem with two free boundaries. The solutions are quite similar to the Fourier series.This method is easy and simple of application.
