ABSTRACT. The effects of Mach number and Nozzle pressure ratios (NPR) on Mass flow rate, Maximum pressure, and Maximum velocity and on Maximum force are studied using Fluent Analysis. The classical one dimensional inviscid theory does not reveal the complex flow features in a convergent divergent.
Isentropic flow through converging nozzles. • Converging nozzle in a subsonic flow will have decreasing area along the flow direction. • We shall consider the effect of back pressure on the exit velocity, mass flow rate and pressure distribution along the nozzle. • We assume flow enters the nozzle from a reservoir so that inlet

The classical one-dimensional inviscid theory does not reveal the complex flow features in an over-expanded nozzle accurately. The code Fluent has been used to simulate the transient flow passing through a 2-D Convergent-Divergent (CD) nozzle (AJAt=l.7, %=3.03', Symmetric about centerline) for nozzle pressure ratios
Utilizing normalized coordinates, the equations governing inviscid, isentropic expansions of perfect gases through convergent-divergent nozzles can be solved as inverse power expan- sions in the normalized throat wall radius of curvature. The solution for the complete nozzle flowfield is obtained in the form of a
A convergent-divergent nozzle is also called a de laval nozzle, after Carl G.P. de Laval who first used such a configura
A converging nozzle can only become supersonic at the exit stage; the speed increases monotonically along the nozzle. If a converging nozzle is fed from a constant pressure constant temperature chamber, the flow rate grows as the discharge pressure is being reduced, until the flow becomes sonic (choked) and the flow
