A Review On Historical And Present Developments In Ejector Systems

Ejectors are simple pieces of equipment. Nevertheless, many of their possible services are overlooked. They often are used to pump gases and vapours from a system to create a vacuum. However, they can be used for a great number of other pumping situations. This paperprovides reviewon the development in ejectors, applications of ejector systems and system performance enhancement. Several topics are categorized provides useful guidelines regarding background and operating principles of ejector including mathematical modelling, numerical simulation of ejector system, geometric optimizations. Research works carried out recently are still limited to computer modelling, forthe real industrial applications more experimental and large-scale work are needed in order to provide better understanding.
