(a) One of your non-engineer friends claims to have discovered a shockwave in which air downstream of the shock is colder than the air upstream of the shock. Comment on the plausibility of this dis- covery. (b) The body shape shown in Figure 1 flies supersonically through air, forming oblique shockwaves from the tip of the body. Sketch the key features of the flow and indicate the direction of the flow downstream of the shock. Figure 1: Wedge (c) If the flow downstream of a shock is sonic and is at an angle to the shock of 30°, then determine the upstream Mach number and the deflection angle 6. (d) The same body shape subsequently flies faster, while still forming an oblique shock at the tip of the body. Explain with reasoning whether the angle the shock makes with the upstream flow is greater, less than, or the same as in question 2(c).
