After burners are used to accelerate the aircraft during the take off or transonic flight when a temporary increase in thrust required. It is also used to increase the combat capabilities of fighter air craft. The presence of Diffuser struts, Fuel injection rings, Flame holders makes the flow in the after burner more complex. The detailed study of over flow is required for the design and performance evaluation of the after burner. In this work the cold flow analysis of a practical after burner system has been done and the flow around the different parts of the afterburner has been studied. The flow analysis was carried out using compressible, viscous and turbulence mode of commercial CFD software Star-CD. The turbulence is modeled using standard K- model. The numerical results were compared with experimental data taken at the after burner front and exit planes. The numerical results agree satisfactorily with the experimental values. This work will be helpful for the Design and Performance evaluation of after burner.
