Comparative analysis of performance characteristics of jet vortex type superchages / A. Rogovyi, Ye. Voronova // Автомобильный транспорт : сб. науч. тр. / М-во образования и науки Украины, ХНАДУ ; [редкол.: Туренко А. Н. (гл. ред.) и др.]. – Харьков, 2016. – Вып. 38. – С. 93–98.2219-8342https://dspace.khadi.kharkov.ua/handle/123456789/1690On the basis of mathematical modeling there was carried out a comparative analysis of characteristics of jet vortex type superchargers. Dependences of the energy performance of vortex ejector on the geometry parameters and the largest values in terms of efficiency as well as the coefficient of ejection are analyzed. There were built combined characteristics of vortex chamber pumps and vortex ejectors. Vortex chamber pump has advantage pressure in an exit channel over the vortex ejector, consequently there is a more effective power transmission from a working medium, besides the withdrawal of pumping medium in a tangential channel allows to avoid energy losses owing to rotation of a stream in an exit channel.envortex ejectorcomparative analysisvortex chamber pumpnumerical calculationenergy performanceвихревой эжекторсравнительный анализвихрекамерный насосчисленный расчетэнергетические показателивихровий ежекторпорівняльний аналізвихрекамерний насосчисельний розрахунокенергетичні показникиArticle621.521
