The Methodology of Numerical Simulations of Separation Process in SPR-Separator

Abstract

The article describes the methodology of hydrocyclone SPR separator numerical simulation, which is used for oil lubricant and liquid impurities separation on technological lines of circulation lubrication of metallurgical machines. The methodology of hydrocyclone SPR separator numerical simulation was developed with taking into account up-to-date articles about the study of hydrocyclone equipment. It was done for determining the relation between the main structural dimensions of the device and the flow parameters, as well as the separation efficiency of the heterogeneous inlet mixture. Numerical simulations were performed by using ANSYS namely its module Fluent Flow. The methodology of the finite volume computational grid building was described. This methodology takes into account the geometry features of the model, such as the presence of surfaces curvature and small gaps compared to other linear dimensions. Settings of the Fluent module was described with design features of the SPR-separator and its working parameters. Eulerian multiphase flow model, k- RNG turbulence model with Swirl Dominated Flow settings was chosen. According to the results of the numerical simulation was determined the main hydrodynamic characteristics of the flow which presented as isolines in the middle section of the separator and value of the separation efficiency of the heterogeneous mixture. New design of a spiral nozzle was proposed for expansion of the range of effective work.
