An Analysis of Transient Flow in a Clean Room by a Modified GSMAC Finite Element Method

A method of numerical simulation has been developed to delineate guidelines for the ventilation design of a clean room. This paper presents a modified finite element analysis for solving unsteady incompressible Navier-Stockes equations. This scheme is based on the algorithm of the HSMAC (highly simplified marker and cell) method and the general idea of orthogonal decomposition. Unsteady flow simulations in terms of stream lines, equipressure lines and equivorticity lines are obtained on a color graphic display
