An ejector system is to be designed in order to pump out the gasses from low pressure to ambient conditi ons. Ejectors mainly use the principles of fluid dynamics for pumping. They do not consist of any mechanical parts and hence no wear and tear. But consequently the design of the ej ctors should be very much precise for the prope r and reliable function. In this part of the work, the configurati on of a nozzle is calculated from a predefined rock et air ejector configuration. Models are developed and analyzed us ing numerical simulation software’s. Taking the predfined input and boundary conditions, pressure, temperature, Mac h number and velocity contours are developed for th e analysis to identify the convergence for a flow through nozzle f or cold and hot air. Further, Parametric analysis is also carried out by plotting various graphs to understand the corres ponding effect.
