Energy performances of the vortex chamber supercharger

The problem of reliability and productive life of superchargers is very acute in systems of pneumatic and hydraulic transport. One of the ways to solve this problem is to use the jetting technology. The vortex chamber superchargers studied in this work are new devices of jetting technology and have better performance indicators in comparison with classical jet devices. It has been experimentally proved that the ejection ratio for the solid particle of the developed superchargers is twice that of the jet ejectors. This is explained by the use of a centrifugal force in a vortex chamber, which contributes to the accumulation of more kinetic energy of the pumped solid particle. The energy performance of vortex chamber superchargers was obtained experimentally and by modeling. Experimental studies were carried out on a specially designed experimental setup with a supercharger model. Studies were carried out in water, air and when pumping coal dust. Numerical calculations were carried out while solving the RANS equations, using the SST model of turbulence and streamline curvature correction.
