Next: Flow in a Semi-2D Up: Solution of Mach Angle Previous: Upstream Mach Number, M1, Index Given Two Angles, δ and θIt is sometimes useful to obtain a relationship where the two angles are known. The first upstream Mach number, isThe reduced pressure difference is The reduced density is For a large upstream Mach number and a small shock angle (yet not approaching zero), , the deflection angle, must also be small as well. Equation (13.51) can be simplified into The results are consistent with the initial assumption which shows that it was an appropriate assumption.
