Isentropic flow in a nozzle
WebSolve for the flow field downstream of a supersonic nozzle using the method of characteristics. The Mach number at the exit plane is 1.5 and the pressure at the exit plane is 200 kilopascals. ... Isentropic flow is assumed. The definition of characteristics are the curves in the flow where the velocity is continuous but the first derivative of ... WebA converging diverging nozzle is generally intended to produce supersonic flow near the exit plane. If the back pressure is set at (vi), the flow will be isentropic throughout the nozzle, and supersonic at nozzle exit. Nozzles operating at PB (corresponding to curve (vi) in Fig. 40.8) are said to be at design conditions.
