| Abstract: | A comfortable and healthy indoor environment should be provided by the air-condition in a good building. On the basis of the experimental work finished by Blay et al., the standard model and wall-function are used to simulate the mixed convection flow in a two-dimensional cavity, and the numerical results of flow and temperature field match with the measured data well. The maximum error between the numerical and the experimental data is about (0.043m/s) in velocity and 1.17K in temperature. In addition, the buoyancy can be neglected for source term of equation. |
