Analysis of the interaction between a submerged jet and a receiver-diffuser in a reverse-flow diverter. Consolidated Fuel Reprocessing Program

Two mathematical models of the interaction between a submerged jet emanating from the nozzle of a reverse flow diverter (RFD) and a receiver-diffuser of a venturi-like reverse flow diverter are presented and compared with experimental data. Both models predict the output characteristics fairly accurately, although the experimentally measured flow is observed to saturate at higher values of jet dynamic pressure and at lower values of output load impedances. An analysis based on the inviscid flow model indicates cavitation as the likely cause of the flow saturation.
