Solution to two-dimensional wind sand fluid boundary layer equation of high speed car

For momentum integral of wind sand fluid boundary layer of high speed car, in the control of certain boundary conditions, quartic polynomial construction is used to approximate rate distribution in boundary layer and curve factor having solid phase disturbance element is required. Also, by the relative transition of momentum integral, discussion of factor function and analysis of curve, in the condition of boundary layer thickness coefficient cited, solution expression of wind sand fluid boundary layer equation is obtained and the finite approximation algorithm to boundary layer calculation is given. In the end, according to the analysis of the solution, the presence and sole characters are determined.
