To design an efficient and acceptable indoor air environment in a badminton gymnasium, it is important to study the velocity and temperature field in the conditioned room. For diverse airflow patterns, the k- c models with wall function near solid boundaries are adopted to simulate airflow distribution in the gymnasium. The simulated result is analyzed in this paper, and it provides the important reference for the design of air condition system and optimization of the project. CFD is effective design tool for air flow in large space, for it can give the velocity and temperature values at any point quantitatively.
