| Abstract: | The test results at variable wind tunnel turbulence shown that the turbulence level has large effects on turbulent characteristics, transition characteristics, aerodynamic noise characteristic and its correlation of the boundary layer and near wake of an airfoil. The effect of turbulence has certain rule. This paper give some Semi Empirical Relations. |
