Abstract

An implicit algorithm of Bi-penalty approximation with orthogonality projection for the numerical simulation of Bingham fluid flow problems is proposed in this paper.A Newton fluid flow with two kinds of artificial viscosit y subjected to the inequality constraint is introduced to approximate the Bingham fluid flow.This approach can effectively simulate the Bingham fluid flow with floating rigid cores or fixing rigid cores.
