Abstract
In jet pumps, energy exchange between the jet and the secondary flow strongly determines its overall efficiency. In this article, the effects of introducing inlet swirling flow in the main jet of liquid jet gas pumps were investigated experimentally. Four different swirl components with degree of swirl covering the weak, moderate, and strong ranges were used. Experimental measurements were carried out on the transparent jet pump model with variable throat length and nozzle spacing under constant jet pump number n. Experimental results are provided concerning the effect of inlet swirl on jet break-up length and compared with the previous results. Good agreement is found between experimental results and theoretical predictions of one-dimensional model.
