WebJun 17, 2024 · Ideal Flow Around a Spinning Ball. Flow. All that is necessary to create lift is to turn a flow of air. The airfoil of a wing turns a flow, but so does a spinning ball. The exact details are fairly complex and are given on a separate slide. Summarizing the results, the amount of force generated by a spinning ball depends on the amount of spin ... WebThis is the Prandtl–Meyer function, the angle measured from the flow direction where \(M = 1\), through which a flow turned isentropically reaches \(M\). If we know the downstream Mach number, we can solve Equation easily to get the associated turning angle. Finding the new Mach number from the angle requires interpolation or numerical solution.
