【Abstract】 Briefly presents the N-point opening momentum model for description of inlet boundary conditions, a new zero-equation turbulence model and error pre-treating method. Numerically simulates the velocity and temperature distribution in an office with grille as air supply opening. Compares the numerical results with the measured data. The result shows that they are well conforming. The models can fast simulate indoor air distribution on a common personal computer and can be used to predict indoor airflow pattern and air distribution for engineering application.更多还原
