  • Mathematical model of the formation of cavitation bubbles in a centrifugal pump

    The process of cavitation is one of the reasons for the premature wear of pumping equipment components. Elements of a pumping wheel are subject to the greatest wear. In addition, cavitation causes undesirable effects such as vibration and noise. In order to reduce cavitational damage and increase the service life of pumping equipment, the authors of this article propose to install a special-shaped flow divider at the pump inlet that breaks the flow entering the pump into separate jets of a certain shape and structure.

  • Development of a highly efficient design of a sulfuric acid alkylation jet reactor

    The article discusses the process of sulfuric acid alkylation used to produce high-octane gasoline, as well as the design of jet reactors, their advantages and disadvantages. Based on the existing drawbacks of jet reactors, the development of a new high-efficiency jet reactor design has been proposed.

    Keywords: reactor, sulfuric acid alkylation, isosurface, isocontours, gasoline, fractions, jet type, industry, oil refining
