WebThe Mach number M d downstream of a normal shock is related to the Mach number M u upstream of the shock (still assuming γ = 1.4) by the equation . Therefore, at each point … WebFor a given Mach number, M 1, and corner angle, θ, the oblique shock angle, β, and the downstream Mach number, M 2, can be calculated.Unlike after a normal shock where M 2 must always be less than 1, in oblique shock M 2 can be supersonic (weak shock wave) or subsonic (strong shock wave). Weak solutions are often observed in flow geometries … Web23 de out. de 2015 · Sorted by: 1. The short answer is that sound waves travel at the speed of sound. Since the sound speed increases downstream of a shock and the flow speed decreases, this results in a Mach number less than one. The physical reason is that without a piston, the flow of a fluid cannot exceed its communication speed due to dissipative … one bank payment
