A swirl body inserted into the entry of the primary fluid to a venturi-ejector influences the subsequent mixing of the two fluids and increases the suction rate of the ejector. An experimental facility has been developed to study the influence that a variation in the swirl angle has on the operational performance of a model venturi-ejector. Water and air were the primary and secondary fluids employed. Three swirl body configurations representing three different swirl angles were inserted upstream of the entry nozzle and the resultant downstream flow mixing characteristics were studied. The performance of the venturi-ejector with and without the use of the swirl body inserts was compared. The paper presents a description of the experiments performed and an analysis and discussion of the results obtained from this initial experimental study.
