This study aims to develop a numerical method for predicting smoke movement caused by fires. The Boussinesq approximation can not be applied to such variable density flow with high temperature difference. However it is very difficult to simulate the variable density flow with low Mach number by usual simulation method used for analyzing compressible flow with high Mach number. In this study, the constant pressure in space is assumed for the equation of state so that the pressure fluctuation concerning sound propagation should be negleted. For the first step of this study, the simulation methods for analyzing equations mentioned above are tested by calculating laminar free convection along a heated vertical flat plate.
