Numerical study of air distribution of cylindrical theaters in summer

According to the audience area structure and air conditioning characteristics in summer in cylindrical theaters, investigates the air distribution with different supply air temperatures and angles in summer based on the Chen-Kim K-ε turbulent model and Boussinesq approximation. Analyses and compares the differences of temperature, velocity and flow distribution with different supply air temperatures and angles. Finds that both the temperature and velocity achieve reasonable distribution and the cleanness of air could be well controlled when the supply air temperature and angle is 19 ℃ and 10° respectively.
