Estimating the optimal efficiency coefficient of ejector in dependence of working and injected space density (English)

A procedure for estimating the optimal efficiency coefficient of ejector (jet jump) is presented. The efficiency coefficient of ejector is defined as ratio between energy of obtained injected current and energy of used working current. Based on the conservation laws (mass, momentum and energy) for one-dimensional incompressible fluid flow in the jet pump, three different convenient expressions for efficiency coefficient of ejector are derived. These expressions are analyzed in order to obtain their optimal values. In this way optimal values of different fluid flow parameters (coefficients of injection, injected/working fluid density ratio, velocity parameter) are obtained. The theoretical results are confirmed with corresponding experimental data.NEWLINENEWLINEFor the entire collection see [Zbl 0884.00052].
