Abstract：
Presents the design of a Shanghai Expo pavilion project, calculates the supply flow rate with the displacement ventilation CFD predictive equation deduced by Professor Chen Qingyan. Simulates and optimizes the temperature and air velocity distribution, and tests the temperature during the operating. Draws a conclusion that the project can be one case to predict supply flow rate in large space by using Chen’s CFD predictive equation.
