An ejector driven by a liquid is a fluid transfer equipment to be used under a poor suction condition, which means that there exists a possibility to occur a cavitation. It is a highly reliable device because it has no movable part in it, that is only a passive equipment. The ejector is an inevitably necessary one to overcome a poor pumping condition and to mix uniformly two fluids, however it has a low efficiency since it requires a pump for its operation. This study is for the development of a new-type liquid ejector with the application of a nozzle shape alteration, which maximize the suction performance of it. which provides the increased competition with the domestic industries. Also, the increased performance opens a new manufacturing method to use a commercial pipes for the production of an ejector, which is based on a trivial loss of a performance. However, this minor loss can be sufficiently compensated by the increased performance of a new-type ejector. Therefore, the developed ejector by this study can considerably reduce the manufacturing time and cost while its performance is largely increased.
