本例为四种求解Blasius平板边界层方程的数值计算方案，欧拉法，改性欧拉法，二阶龙格库塔法和四阶龙格库塔法。为了满足无渗透边界条件，f 位于eta=0处的初值在不同方法下需要进行一定的调整。-This folder contains the matlab programs to solve the Blasius equation for boundary layer of flat plate. There are four numerical methods to solve this problem. Euler, modified Euler, RK-2 and RK-4. In order to satisfy the no-penetration condition, d.h. f =1 @ eta--> infinity, the initial value of f　 @ eta = 0 should be debug in different methods.
