Abstract

A prediction method is presented for the static pressure recovery in subsonic axisymmetric truncated conical diffusers. In the analysis, a turbulent boundary layer is assumed at the diffuser inlet and a potential core exists throughout the flow. When flow separation occurs, this approach cannot be used to predict the maximum pressure location. The analysis can easily be modified to accommodate two-dimensional diffuser and conical diffusers fitted with tailpipes. The predicted overall static pressure recovery compares favorably with available experimental results and agreement is generally within +- 5 per cent.
