The paper reviewed the supply opening models of describing inlet boundary conditions for indoor airflow simulation firstly. Then examples of isothermal free air jets from a grille are presented to validate full representation of supply openings. Some results by the simplified method called N-point supply opening model, are also shown to compare with the full representation method. Four different outlet conditions of a grille are studied. The k-e turbulence model is applied. Comparison between simulated results and measured data shows that full representation is a reliable method for inflow boundary conditions description. Therefore, some other new models or methodscan be developed based on full representation method as it is a universal and trusty method for describing inlet boundary conditions of indoor airflow simulation.
