The two-stage ejector has been suggested to replace the single-stage ejector geometrical configuration better to utilize the discharge flow's redundant momentum to induce secondary flow. In this study, the one-dimensional gas dynamic constant rate of momentum change theory has been utilized to model a two-stage ejector along with a single-stage ejector. The proposed theory has been utilized in the computation of geometry and flow parameters of both the ejectors. The commercial computational fluid dynamics tool ANSYS-Fluent 14.0 has been utilized to predict performance and visualize the flow. The performance in terms of entrainment ratio has been compared under on-design and off-design conditions. The result shows that the two-stage ejector configuration has improved (≈57%) entrainment capacity than the singlestage ejector under the on-design condition.
