Dear Sir I am doing analysis of a convergent- divergent nozzle.

Inlet Dia 503 mm throat dia 134 mm exit dia 394 mm Ae/At = 8.6

Inlet pressure 45 bar Inlet temperature 3300 k outlet ambient

fluid is air, ideal gas. Coupled Implict solver

Isentropic one dimensional analysis shows the pressure at outlet should be around 0.5 bar. But from Fluent software I am geeting pressure at outlet is around 2 bar. May you please guide me that why I am getting greater values at outlet?
