摘要: 考虑理想车体与地面相对运动的基础上,建立地面效应模型.采用标准k-ε两方程湍流模型对理想车体外流场进行数值模拟,并对数值模拟结果进行了研究分析.Abstract: A model of ground effect is proposed on the basis of the relative motion of an ideal car to the ground.Numerical simulation of turbulent flow around the ideal car is solved by using the standard k-εturbulence model,and its results are analyzed and studied.
