Entropy analysis of a solar-driven variable geometry ejector using computational fluid dynamics

•Entropy generation is proposed as a criterion to evaluate ejector geometry and performance.•Correlation between the entropy generation and entrainment ratio was investigated.•The contribution of each flow phenomena in entropy generation was showed.•Effect of primary nozzle position on the overall e...
