WebAn overexpanded nozzle has an area expansion ratio A9 / A8 in excess of that needed for a perfect expansion. This results in an exit static pressure, which falls below the ambient pressure p9 / p0 < 1. The need for an abrupt adjustment of the static pressure in the emerging supersonic flow causes a shock formation on the nozzle lip.
