Physical and mathematical model of working process of jet ejector
A refined physical model of the jet ejector working process has been compiled. On the basis of the refined physical model, a mathematical model has been developed that takes into account the exchange of work and heat between the ejected and ejected gases. Based on the solution of this mathematical...

| Summary: | A refined physical model of the jet ejector working process has been compiled. On the basis of the
refined physical model, a mathematical model has been developed that takes into account the exchange
of work and heat between the ejected and ejected gases. Based on the solution of this mathematical
model, it is possible to formulate a method for calculating the optimal geometric dimensions of the jet
ejector to obtain the specified thermodynamic parameters and a method for calculating the characteristics
of the jet ejector with known geometric dimensions. The effect of viscosity on energy exchange is
shown. The agreement between the calculated and experimental data is satisfactory. |
