The performance of axial annular diffuser with various geometrical configurations for same equivalent cone angle of 10° is explored with the help of CFD. The analysis was carried out for flow regimes with various experimentally obtained inlet velocity profiles with or without swirl. The flow behaviour inside the annular diffuser is analyzed and pressure recovery coefficient is computed which agrees reasonably well with the experimental/available data.
