Abstract

Computational Fluid Dynamics (CFD) is a branch of fluid mechanics that uses numerical methods and algorithms to solve and analyze problems that involve fluid flows. Compu ters are required to simulate the interaction of liquids and gases with surfaces defined by boundary conditions. In this paper , CFD analysis of pressure, velocity (mach number) and temperature of flow for a Convergent - Divergent nozzle of two different dive rged angles (50 & 100) has been performed, because the fluid properties like pressure, velocity, and temperature are dependent on the cross section of the nozzle which affects the flow within the nozzle. A nozzle is a device designed to control the direct ion or characteristics of a fluid flow as it exits or enters. The analysis has been performed according to the diverged angle of the C - D nozzle and kee ping the same input conditions. Our objective is to investigate theoretically what we have studied about sonic (M=1), sub - sonic (M<1) and super - sonic (M>1) and flow parameters, we are proving that by CFD simulation. Initially the 2 - D model of the C - D nozzles is taken in the present research work. The analysis type is 2 - D PLANER. The modeling of the C - D nozzles has been done and later on mesh generation and analysis have been carried out in Ansys - Fluent 14.0 and vario us contours, plots and vectors of pressure, velocity and temperature have been taken and their variation according to different divergent angle nozzles has been studied.
