Simulation of naturally ventilated underground car park with CFD

In this paper, Ansys CFX commercial software is used to simulate the ventilation process in a parking basement. In addition, a simulation problem of ventilation in the office room is also performed to verify the reliability. In Ansys CFX, the Shear-Stress Transport turbulence model is used to determine the temperature and velocity of the tunnel and calculate the level of physical comfort according to ADPI standard.
