In this study, isothermal two-dimensional flow field in plenum chamber indicated by Huang et oi., in which the anisotropy of the stresses is significant, was predicted by DSM and k-ε model using Navier-Stokes equation's steady state condition method developed by Matsuo et al., The results of calculation confirmed that k-e and DSM were in agreement with Huang et al's results and DSM was effective in analyses of flow fields where the anisotropy of the stresses was significant and eddy viscosity model was not applicable. Furthermore, the comparison of three types of Φ^W_<ij(2)> models impinging flow against wall indicated the Craft-Launder's model was more accurate than the other models in impinging flow against wall, and Gibson-Launder's model was not applicable to room air flow.
