WebNormal Shock Diffuser •Let's change the setup so that the nozzle exits the flow into a constant area section instead of a free jet into the laboratory as shown here. •The constant area section contains a normal shock wave standing at the end of the constant-area section. •As a result, the pressure downstream of the normal shock wave is ...

WebBecause the shock is no longer perpendicular to the flow near the nozzle walls, it deflects the flow inward as it leaves the exit producing an initially contracting jet. This is referred as overexpanded flow because in this case the pressure at the nozzle exit is lower than that in the ambient (the back pressure)- i.e. the flow has been expanded by the nozzle too much. high person low technologyWebThe virtual nozzle is an expanding nozzle with subsonic flow and with a Mach number equal to the downstream Mach number behind the normal shock wave. 1.
