INCOMPRESSIBLE FLOW IN CONICAL DIFFUSERS

Abstract

Experiments have been performed using water flow in clear plastic diffusers, discharging into a plenum tank, in order to obtain performance and flow regime information for a range of diffuser geometries. The principal conclusions of the study were: (1) A line of first appreciable stall has been located with sufficient precision that it is useful in conical diffuser design. (2) Performance data have been obtained to allow solution of the four common optimum problems encountered in diffuser design. At present, these solutions can be extrapolated only with caution to other diffuser geometries. (3) The optimums located for conical diffusers are not the same as those suggested by data from tests of plane walled diffusers.
