Selection of structural parameters for a cylindrical hydrocyclone for degassing of heterogenous liquid media based on results of numerical modeling

Recommendations for optimization of structural parameters of a cylindrical hydrocyclone used to degas heterogeneous liquid media possessing non-Newtonian properties are set forth on the basis of results of numerical modeling. The mathematical degassing model takes into account the effect of inertial and Coriolis forces, and the associated liquid mass during the movement of a gas bubble.
A system of differential equations in partial derivatives, which describes the degassing of heterogeneous media in a hydrocyclone, is reduced to ordinary differential equations, and is solved by the numerical method. The influence exerted on the degassing process by structural parameters of a cylindrical hydrocyclone and rheologic properties of the liquid is analyzed.
