Numerical Study of a Conical Diffuser with Annular Injection at the Inlet to Prevent FlowSeparation

The performance of a conical diffuser with annular secondary injection at the inlet is evaluated.Numerical calculations showed an improvement even at moderate injection rates. The effects of injectionvelocity and diffuser geometry on pressure recovery and stall were investigated. The simulation results agreedwell with the experimental data
