Laser Doppler Velocimetry Investigation of Transient Impeller Flow

Abstract

Instantaneous, local velocity measurements at the inlet and discharge of a 1/3-scale transient-operation, submarine weapon ejection pump impeller were taken with a laser Doppler velocimeter. The impeller was tested in the Naval Undersea Warfare Center's Impeller Test Facility under simulated, full-scale, transient operating conditions. Measurement results are sufficient to define inlet and discharge transient boundary conditions for subsequent computational simulations. However, due to the very highly transient nature of the present tests, inadequate LDV measurement data rates precluded obtaining data near and between impeller blades.
