摘要：

Researchers commonly represent jet pump performance with a Head-Ratio, Flow-Ratio curve (HR/FR curve). Our goals are to show that the HR/FR curve has several problems and to propose a new way to represent jet pump performance. Analysis shows that a HR/FR curve does not give enough information to predict the operating point of a system which includes a jet pump. Moreover, the way a HR/FR curve specifies data can force a designer to estimate head losses inside a jet pump and can make data acquisition very difficult. We propose using two curves to represent jet pump performance. Use of the two curves eliminates the problems of the HR/FR curve.
