Computational fluid dynamics (CFD) is applied to predict the performance of low-pressure ejectors. Its accuracy is compared with predetermined experimental results. This Note shows that low-pressure ejectors depend strongly on geometry. CFD can predict their performance good accurately whether there is good positive entrainment or back pressure resulting in negative entrainment. It is concluded that CFD is a useful tool for designing low-pressure ejectors.
