A 1-D gas dynamic model including frictional effects for a more realistic design has been developed for estimating supersonic ejector geometry based on CRKEC approach. This approach has benefits in terms of mitigating the occurrence of thermodynamic shock, which is a major irreversibility that besets conventional ejector systems. Hence, the paper presents a unique approach to evolving ejector design considering it primarily to be a function energy change within the system, specifically being constant rate of kinetic energy change (CRKEC). This would shift ejector design approach from conventional geometry based one to that of flow physics-based approach. Since ejectors are primarily viewed as energy exchange devices, it would be appropriate to design an ejector with its geometry being a function of the rate of energy change. Ejectors invariably convert momentum and kinetic energy of incoming fluids into enthalpy and hence pressure.
