Unformatted text preview: thermodynamics.  Across the expansion fan, the flow accelerates (velocity increases) and the Mach number increases, while the static pressure, temperature and density decrease. Since the process is isentropic, the stagnation properties remain constant across the fan. When a supersonic flow encounters a convex corner, it forms an expansion fan, which consist of infinite number of expansion waves centered at the corner. The figure shows one such ideal expansion fan....
