Blasius exact solution boundary layer

WebA method for injection of gas into the boundary layer on a slender body in supersonic flow while minimizing perturbation to the mean flow is examined experimentally. Injection of gas is equivalent to a sudden increase in the displacement thickness of the boundary layer, which produces an oblique shock that propagates into the inviscid region of the flow. It is … WebQuestion: Boundary layer type - flat plate (Blasius problem) f′∗+ff′′=0 The appropriate dimensionless similarity variables is η=2yvxUx Boundary conditions are f(0)=f′(0)=0,f′(∞)=2 Find that CrRe=21f′(0) Eq.
