Abstract | 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 entrainment ratio under different operating conditions. The simulation of mixing layer growth was validated by using experimental data available in the literature, while the application of the computational method to the ejector flows was validated using static pressure distribution and entrainment ratio data in the |
