Nozzle flows at low and moderate Reynolds numbers
Abstract
Flow past long radius nozzles is studied in the Reynolds number range of 1 to 10,000 based on experiments in an oil recirculation system. The ratio of nozzle outlet diameter to pipe diameter is varied from 0.2 to 0.8. Aspects studied include the coefficient of discharge, sensitivity of the discharge coefficient to marginal shifts in pressure tap location, loss coefficient, loss as function of the meter pressure differential, critical Reynolds number corresponding to the origin of turbulence downstream of the nozzle, setting length, and nature of development of pressure and velocity fields. The contribution contained in the paper fills the gap that exists in literature on the performance of long radius nozzles at low and moderate Reynolds numbers.
