摘要
本文旨在讨论有限元方法求解封闭空腔自然对流问题中几种典型模型的比较,并就流函数涡旋度方法及加罚函数方法进行数值实验,分析两类方法的不足之处,给出改进建议。
In this paper the comparative study of some finite element methods which are used to analyze the natural convection in an enclosure is presented.The numerical simulations are made by use of both the stream function—vorticity model and the penalty finite element model.Their res- pective drawbacks are then discussed and measures are proposed to improve these methods.
