Abstract

Abstract

A new pressure Poisson equation method was established on staggered grid by keeping the viscous terms in the source of pressure Poisson equation.The derivations show that newly established pressure equation has the identical form of the equation in projection method.The results show that selection between the two methods does not affect velocity and pressure values,and CPU times have slight differences.
