摘要

CFD (computational fluid dynamics) method is adopted to analyze airflow pattern inside bus numerically. Torncalculate more quickly and get engineering satisfied results, a new zero equation turbulence model is adopted to simulaternthe air turbulent flow inside. The example presented shows that the model can simulate non-isothermal flow well. Thenrnthe velocity and temperature distribution inside the bus is numerical predicted by software based on the turbulencernmodel. Both summer and winter condition is considered.
