Pressure Recovery in Constant Area Supersonic Diffusers,
Abstract
Knowledge of diffuser performance is largely based on specific configurations of a given facility, often leading to little generality. With new interest in diffuser performance, this report aims at giving a more general view of the view of the behavior of the simplest supersonic diffuser, the constant area duct. Experiments were performed in a wide range of Reynolds number, Mach number and a boundary layer parameter. No clear dependence of the pressure recovery on the Reynolds number was found in the range investigated, but charts based on the experiments and supported by a simplified model correlate the pressure recovery and the length of the recovery zone as functions of Mach number and boundary layer parameter.
