Simulation Study on Indoor Air Ventilation Efficiency Based on Computational Fluid Dynamics
A numerical investigation is presented of the structure of a displacement ventilationconvection by using the Reynolds averaged Navier-Stokes equation and K-e turbulence model.Numerical results are reported for the effect of Gr/Re2 on structure of indoor air convection andventilation efficiency.The results show that the structure of indoor air convection changes frommechanical ventilation to natural ventilation,and the curves of ventilation efficiency are like Mwith Gr/Re2 increasing.
