Recent findings on confined vortex chamber flows

An analytical model directed toward studying selected fluid parameters in vortex chambers is presented. From the model, dimensionless quantities such as, core size, static pressure drop across the chamber, radial static pressure distribution, and radius of reversed flow at the exit, are shown to be functions of chamber geometry only. In addition, it is experimentally demonstrated that in the case of small contraction ratios, the static pressure drop across the chamber can be effectively lowered by plugging the exit flow.
