不可压缩流两重稳定有限体积算法应用研究
Two-level stabilized finite volume method for incompressible flow
摘要
Abstract
In this paper, two-level stabilized finite volume methods are considered which are based on local Gauss inte-gral technique and two-level grid algorithm for the incompressible flow. The error analysis shows that the two-level stabi-lized finite volume methods provide an approximate solution with the convergence rate of the same order as the usual sta-bilized finite volume solution solving the incompressible flow problems on a fine grid for a related choice of mesh widths. The performance of three kinds iterative scheme of two-level stabilized methods are compared in efficiency and precision aspects by a series of numerical experiments. It discovers that the simple scheme is better than two others on accuracy and efficiency. There is the poor numerical accuracy for the Newton scheme, but the Picard scheme is more suitable to incom-pressible flow with low viscosity coefficient.关键词
