Flow turning angle

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. WebThe average radius of the blades is 17.5 in., and the inlet blade height is 2.12 in. The absolute inlet flow angle to the rotor is the same as te stator exit flow angle (6 5.0), an d the rotor flow turning angle i s 7 5.0. The stage has been designed so that the blade height varies and the axial velocity remains constant through the stage.
