Scientific activity:

In his doctoral dissertation, he solved the scientific and practical problem of increasing the technical and economic efficiency of hydraulic and pneumatic blowers that pump liquids in unfavorable operating conditions or heterogeneous media through the development and use of a fundamentally new type of centrifugal jet blowers. Their design does not contain moving mechanical parts or seals, due to which they have high reliability and durability inherent in jet technology. The concept of blowers is based on a new principle for jet blowers – a combination of the positive qualities of processes in centrifugal and jet blowers and the features of the hydrodynamics of limited rotating flows. The use of vortex-chamber blowers makes it possible to increase the energy efficiency of hydraulic and pneumatic systems, increase the volume of transported goods in hydraulic and pneumatic pipeline transport, increase labor productivity and product quality, reduce its cost, and improve working conditions. The developed blowers are more energy efficient due to the transfer of energy in the centrifugal force field. Thus, the scientific foundations for the design of vortex-chamber jet blowers for pumping media of various aggregate states have been created.
