Development of Constant Rate of Momentum Change

A nozzle is a mechanical device which is designed to control the rate of flow speed direction and pressure of the stream that exhaust through it. There are various types of nozzles which are used. In a nozzle the velocity of fluid increases at the expense of its pressure energy. Nozzle specifically is a device which is developed and designed to control the direction of the fluid flowing in any motion the nozzle's primary role is to control the characteristics of fluid flow just like to increase the velocity as it exits the chamber of a propulsive system. In the thesis the Computational Fluid Dynamic (CFD) analysis to study on supersonic variable area nozzle with frictional effects. The investigation is to find the ways to improve the performance of nozzle systems. This is mainly concentrated on the design and analysis of CRMC nozzle with frictional effect. The results are shown based on contour and graphical. A graph represents acc. to analytical and CFD. As observed from results that Mach number is increasing with increasing axial distance along CRMC nozzle.
