A nozzle is equipped for changing, transforming pressure energy into kinetic energy and the other way around, depending on the state of the nozzle above changes happen. Nozzle which is a C-D nozzle is utilized to achieve supersonic stream speeds. The inlet Mach number is less than one; the convergent section speeds up it to the sonic speed at the throat and further sped up to supersonic speeds by the diverging section. A nozzle is a device intended to control the direction or attributes of a fluid flow (particularly to expand speed) as it exits (or enters) an encased pipe. A nozzle is frequently a channel or container of shifting cross-sectional zone and it very well may coordinate or change the progression of a liquid (gas). Nozzles are as often as possible used to control the speed of stream, speed, and direction, mass, shape, and/or the pressure of the stream that emerges from them. To improve the mixing attributes execution of supersonic controlled stream using limiting tab, which is the dainty wire that makes 5% obstruction of the diameter across of the nozzle exit. Different Reynolds Averaged Navier Strokes Equation RANS models are using and look at the consequences of Mach no. 1.86 supersonic stream from 2D Convergent-Divergent nozzles for NPR 4 with a step size of one, to examine diverse scientific models for execution. Converging the over-expanded and close to addressing development condition ANSYS Fluent 16.0. Using 2D hex components and organized work has produced into the ICEM module. Non-dimensional plots of Mach No along fly focus line, regarding the non-dimensional separation of k-ε workable, k-ω, k-ω standard, Reynolds Stress with standard and change SST conditions are looked at and investigations.
