Abstract

This article describes a numerical simulation model of air movement in buildings. It starts with a solution to the fluid motion equations and its simplifying assumptions and it goes on to describe the strategy for integrating the solution with the geometry of the spaces and the surfaces enclosing the spaces. It concludes with a comparison of the results from this simulation program with empirical measurements published in the literature. The theoretical model starts with the mass and momentum conservation equations and goes on to obtain the static solution for streamline motion for an incompressible fluid. The solution takes the form of the equations for direct current. The geometry of the spaces is divided into convection cells and then it is reduced to a set of current loops. The model contains three sources for pressure diffe
