摘要：

It is crucial to enhance the ejector capacity to widen its application in industry. A novel ejector with a
bypass installed in the low pressure district is proposed to enhance the ejector capacity. The results show
that there is an optimal position for the maximum entrainment ratio, which corresponds to the lowest
pressure around the second shock position. When the ejector operates at design conditions (the primary/
induced/back pressures are 0.3/0.02/0.08 MPa), the optimal length ratio is about 1.1. Then, the ejector
performance with the optimal bypass is investigated under different operational parameters. It is found
that the novel ejector has relatively high entrainment ratio and low critical back pressure compared to
the ejector without bypass under the design condition. When the primary pressure is bigger than a certain
value, the entrainment ratio would always improve as the primary or induced pressures increase.
