A two-grid algorithm based on Newton iteration for the stream function form of the Navier-Stokes equations
收藏 引用
Applied Mathematics(A Journal of Chinese Universities) 2011年 第3期26卷 368-378页
作者: SHAO Xin-ping HAN Dan-fu Department of Mathematics Zhejiang University Hangzhou 310027 China
In this paper, we propose a two-grid algorithm for solving the stream function formulation of the stationary Navies-Stokes equations. The algorithm is constructed by reducing the original system to one small, nonlinea... 详细信息

Modified two-grid method for solving coupled Navier-Stokes/Darcy model based on Newton iteration
收藏 引用
Applied Mathematics(A Journal of Chinese Universities) 2015年 第2期30卷 127-140页
作者: SHEN Yu-jing HAN Dan-fu SHAO Xin-ping Department of Mathematics Zhejiang University Department of Mathematics Hangzhou Normal University School of Science Hangzhou Dianzi University
A new decoupled two-gird algorithm with the Newton iteration is proposed for solving the coupled Navier-Stokes/Darcy model which describes a fluid flow filtrating through porous media. Moreover the error estimate is g... 详细信息

LOCAL AND PARALLEL FINITE ELEMENT METHOD FOR THE MIXED NAVIER-STOKES/DARCY MODEL WITH BEAVERS-JOSEPH INTERFACE CONDITIONS
收藏 引用
Acta Mathematica Scientia 2017年 第5期37卷 1331-1347页
作者: 杜光芝 左立云 School of Mathematics and Statistics Shandong Normal UniversityJinan 250014China School of Mathematical Sciences University of JinanJinan 250022China
In this paper, we consider the mixed Navier-Stokes/Darcy model with BeaversJoseph interface conditions. Based on two-grid discretizations, a local and parallel finite element algorithm for this mixed model is proposed... 详细信息
