WebAt the corner, the flow has to turn though an angle $θ$ because of the requirement that the normal component of velocity at any solid surface has to be zero. To facilitate this turn we require an oblique shock at an angle $β$ to form at the corner. The shock angle can be calculated for a given Mach Number and angle $θ$. WebBrassCraft 1/2 in.

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. WebMar 5, 2024 · Maximum Turning Angle. (12.4.1) ν ∞ = π 2 [ k + 1 k − 1 − 1] The maximum of the deflection point and the maximum turning point are only a function of the specific heat ratios. However, the maximum turning angle is much larger than the maximum deflection point because the process is isentropic.
