A Numerical Simulation of Heat and Fluid Flow in the Motor Block Room of a Motorized Car

동력객차 동력실 내부의 열유체 유동의 수치 시뮬레이션

Heat and fluid flow in the motor block room of a motorized car is numerically simulated. The motorized car, composed of a motor block room and a passenger room, supplies additional Power to achieve the design speed. A motor block, a transformer, and a fan are equipped in the motor block room. Flow phenomena in the ducts on the motor block and power transformer are investigated. Also, the three dimensional heat and fluid flow in the motor block room is simulated to give a qualitative information of the flow characteristics.
