Supersonic flow over a diamond-shaped airfoil is one of the classic canonical cases for demonstrating the application of shock-expansion theory. As the supersonic flow moves over the airfoil, it encounters both oblique shock waves and expansion waves. Though the flow-field is quite complicated, the shock-expansion theory is able to ...
