Analytical Investigation of Performance of De-Laval Nozzle

To control fluid properties like density, velocity, temperature and pressure a Nozzle is utilized. By converting heat and pressure in to KE flow velocity is increased, this is the main application of nozzle. The ratio of exit area to throat area is the nozzle expansion ratio. A typical De-Laval nozzle may be a nozzle that incorporates a converging area, throat and diverging area. In this thesis, the performance analysis of De-Laval nozzle by changing the expansion ratios at different Mach numbers is analyzed. The considered expansion ratios are 7.84 and Mach Numbers are 2.8 for CFD analysis is done on the nozzle and the comparisons are made for pressure distribution, velocity. Static structural analysis is done on the nozzle by applying the pressures obtained from CFD analysis using different materials Brass, Titanium. 3D models are done in Creo 2.0 and CFD and Static Structural analysis is done in Ansys
