Numerical Analysis on a Constant Rate of Kinetic Energy Change Based a Two-Stage Ejector-Diffuser System

Supersonic ejector energy flow devices are extensively used in various applications, such as pumping, mixing, compression, etc. The conventional single-stage (SSE) design approaches inefficient for modelling an efficient because of their inefficiency minimizing mixing losses the chamber, thermodynamic shock constant area diffuser, and utilization redundant discharged momentum at exit first stage. physics-based has better solutions it minimizes irreversibility due to shocks. present study utilizes rate a kinetic change approach two-stage (TSE) water vapour. computational fluid dynamics (CFD) tool ANSYS-Fluent been utilized predict characteristics. performance ejector-diffuser system also compared with ejector. It is found that TSE 70 % higher than SSE.
