AN EXPERIMENTAL STUDY ON PRIMARY NOZZLE TYPES OF EXHAUST EJECTOR SYSTEMS

Optimum distances between primary nozzle exit and mixing tube inlet,static pressure recovery of the mixing flow in mixing tube、total pressure distributions at the exit of mixing tube、pumping coefficients and total pressure losses of the exhaust ejector systems with four different types of primary nozzles have been measured in the experiments.The results have an important reference value for selecting primary nozzle types of exhaust ejector systems.
