Air ejectors are commonly used in engine test laboratories to dilute engine exhaust to match the range of the sampling instrument. Recent experiments have shown that up to fifty percent of the large particles will be lost as the exhaust sample passes through the ejector. Therefore, this project is working to improve ejector design so that particle losses are minimized. A three-dimensional model of fluid flow field and particle trajectories in an ejector is now being developed. The results from the ejector simulations will then be used to redesign and optimize the ejector.
