CFD Analysis of Convergent-Divergent Nozzle using Standard K-ÃŽâ?¢ Model

Having its specific flow characteristics, a convergent divergent nozzles find its applications in various field such as aerospace technology, chemical and power plant also. Thus it is required to know flow phenomenon associated with convergent divergent nozzles to utilise their capabilities to their fullest. In this paper 2-d axial symmetric flow analysis for compressible flow through a convergent - divergent nozzle is carried out with the help of Computational Fluid Dynamics tools (Gambit 2.4.0.0 and Fluent 14.5 for modelling and analysis respectively). The problem is solved by standard K- epsilon turbulent model. The contours and vectors are drawn for pressure, velocity, temperature and mach number to ascertain out the design condition for convergent - divergent nozzles.
