Keywords: radial inflow, rotating cavity, non-dimensional mass flowrate, rotating reynolds number, total pressure drop

A basic theoretical analysis and experimental study are reported in this paper. It is shown that, with the influence of the centrifugal force and carioles force, the circumferential component of the velocity can be very high and can lead to pronounced total pressure losses in rotating cavity with radial inflow.
