Abstract

In the present study we focus on simulating the high temperature subsonic compressible flow in the diffuser duct of an afterburner unit of an air breathing jet engine. The diffuser duct was designed as per the guidelines explained in the standard engine design data hand book and corresponding experimentally measured results are referred for validation purpose. Aerofoil struts were incorporated in the design and the pressure loss due to the struts is assessed by CFD analysis. The CFD analysis is carried out with SST K-Omega Turbulence model and direct resolution of shear stress approach employed in Mentors Shear Stress Transport Turbulence model. The pressure loss computed for diffuser with various struts configurations and compared without strut
