This paper presents a comparison of results from a CFD simulation and one-dimensional control volume analysis of an ejector applicable to a high subsonic wind tunnel as an engine test facility. The effect of varying operating conditions such as nozzle pressure and geometrical factors such as the length of the mixing chamber or the number of nozzles on the ejector performance and test section velocity was investigated.
