Performance Evaluation of Nozzles through CFD Analysis for Different Materials

Steam nozzles play an important role in Flid flow related problems in industrial applications. Current problem analyses a convergent-divergent nozzle for different flow parameters, shapes & materials so that the flow across the nozzle is optimized. The convergent-divergent nozzle is to be analyzed for its performance on the basis of several performance parameter like Nozzle dimensions, Inlet pressure, Flow Parameters, Pressure Ratio etc. Output parameters that are being investigated in the current analysis include pressure distribution, Velocity Distribution, Wall Shear, Flow characteristics, Drag Force & Coefficient of Drag. Problem has been solved using CFD analysis taking into account k-É› model & energy Equation. Results of the study include- material doesn't affect the pressure inside the nozzle for given input parameters, velocity is also approximately remaining same, material doesn't affect the temperature inside the nozzle for given input parameters, Mach Number for Aluminium & Steel materials is better as compared to Titanium, material doesn't affect the Wall Shear inside the nozzle for given input parameters, Steel is best suited material for the current application according to Coefficient of drag. Overall, it can be concluded that Aluminium as well as Steel materials are better suitable for the current application.
