“…According to Zaheer and Masud (2017), the LES approach provided more detailed information about flow instabilities inside the ejector, along with the cost of the computational time. Ismagilov et al (2017) investigated nozzle reduction using a blade agitator on the liquid jet ejector efficiency to define the optimum nozzle throat area. Haida et al (2016b) numerically analysed R744 liquid ejectors installed in a prototype multi-ejector module.…”
