Ejector entrainment ratios are influenced by both pressure-driven effects and the mixing between the primary and secondary streams, but the significance of each factor has not been identified in prior literature. This paper presents a computational simulation investigation of flow in a representative steam ejector to specify the contribution of mixing and pressure-driven effects to the overall ejector...
Steam ejector computational simulations using a wet steam model give higher entrainment ratios and higher critical back pressures for the ejector compared with the ideal gas model. This paper identifies the origin of these differences. Simulation results show that the wet steam model predicts an entrainment ratio for the choked flow ejector operation that is 10% higher than that for the ideal gas...
Ejectors produce a pumping effect based on high speed jet entrainment but data on the development of mixing in steam ejectors with condensation effects is not available. In the present work, the mixing region generated downstream of an axisymmetric supersonic steam ejector nozzle is surveyed using a pitot pressure probe. Steam was delivered to the nozzle at a stagnation temperature of 142°C and at...
