The results of optimizing two- phase flows on the basis of the solution of an inverse problem with the pressure distribution given by a two-parameter function are presented. The efficiency of the developed approach is illustrated with reference to nozzle and ejector flows with large liquid phase flow rates (the liquid droplet flow rate being greater than that of the gas by a factor of several tens).
A mathematical model, which permits the ejector geometry to be optimized, has been designed in the framework of the inverse problem with the use of a non-equilibrium model of the two-phase gas-droplet medium and pressure law. A conventional ejector with a cylindrical chamber and diffuser is compared to the optimum geometry ejector based on numerical studies.
