INFLUENCE OF PERTINENT PARAMETERS ON EJECTOR-DIFFUSER PERFORMANCE WITH AND WITHOUT EJECTED MASS

Abstract

Data from various diffuser model studies were analyzed to determine the influence of pertinent parameters on ejector-diffuser performance with and without ejected mass from the test cell. The parameters varied were conical nozzle area ratio (3.15 to 18.00), diffuser shape (straight or with various types of bends), mass ejected from the test cell (from 0.11 to 1.31 percent of rocket flow) for different nozzle configurations (single-, two-, and four-nozzle cluster) and diffuser sizes (4.026- to 10.02-in. diam), and ratio of diffuser- to-nozzle exit area on start and breakdown diffuser pressure ratio with respect to second-throat contraction ratio.
