Airflow in underground railway station platforms is turbulent. Boundary conditions and proper turbulence model are required to determine when adopting CFD to simulate platform ventilation.
Besides, it indicate that it's feasible to utilize CFD software with suitable coefficient and boundary conditions to simulate the airflow organization to instruct the design of ventilation.
Based on hydromechanics affinity theory and major control factor of highway tunnel ventilation, the paper had made certain highway tunnel ventilationboundary condition.
