Abstract	Piston wind have a great impact on thermal environment of subway platform, using cooling damping wind can control piston wind ingress and improve heat environment. Cross-jet flow theory is used to analyze piston wind control by cooling damping wind and computational fluid dynamics (CFD) method are adopted in this paper. Different angle and height of nozzle are simulated. The angle of the air supply of cooling damping wind is adjusted to vertical 90° and 45° opposite to the velocity of the piston wind, respectively. A pipe of 0.5m is added under the jet vent to reduce cooling damping wind speed decay. The temperature distribution and velocity of the platform are selected analysis. Through analyzing and comparing with the simulation results, The optimal way of control postion wind is gained and piston wind influened are decreased to some extent. This study is important to energy saving for cooling damper wind utilized rationally
