An ejector system is to be designed in order to pump out the gasses from low pressure to ambient conditions. 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 ejectors should be very much precise for the proper and reliable function. In this part of the work, the configuration of a nozzle is calculated from a predefined rocket air ejector configuration. Models are developed and analyzed using numerical simulation software's. Taking the predefined input and boundary conditions, pressure, temperature, Mach number and velocity contours are developed for the analysis to identify the convergence for a flow through nozzle for cold and hot air. Further, Parametric analysis is also carried out by plotting various graphs to understand the corresponding effect.
