supersonic wind tunnel starting problem

The tunnel did start with the 3-in. For low upstream pressures, the pressure ratio relative to atmospheric exit pressure is insufficient to obtain supersonic flow in the tunnel. This suggests that the supersonic diffuser should have convergent divergent section to decelerate the flow from supersonic to subsonic flow again with the diffuser throat Mach number nearing 1.
