摘　　要：应用CFD技术研究轿车内空调吹风道的空气流场动力特性。根据N-S方程和RNGk-ε二方程湍流模型,用二阶精度有限体积法将方程转化为可以数值计算的代数方程;利用SIMPLE算法,对计算域中的流体进行压力和速度耦合。得出在定流量进风的情况下,各出风口的速度和流线分布,整体的压力分布,认为三通道的出风口结构较合理。The Flow dynamic properties on the air inside the car was studied by the application of CFD technology . According to N-S equation and RNG k-ε equation onflow model, with second-order precision finite volume equation will be converted into numerical equations .SIMPLE algorithm used to calculate the domain of fluid pressure and speed coupled.That will flow into the wind in the circumstances, the outlet to the speed and streamline distribution, the overall distribution of pressure. The three-channel outlet structure is more reasonable.
