Influence of Rheological Properties of Disperse Media on Degassing Indexes of Nonlinear-Viscoplastic Fluids in a Cylindrical Hydrocyclone

A mathematical model of the process of degassing of nonlinear viscoplastic fluids in a cylindrical hydrocyclone is developed, taking account of inertial and Coriolis forces and virtual mass of the fluid. A system of differential equations in partial derivatives that describes the degassing process is reduced to a system of ordinary differential equations and solved by numerical method. The influence of the separation factor and rheological properties of the fluid on the degree of gas bubbles extraction is analyzed. The obtained data can be used to design equipment for degassing of oil in preparation for its transportation.
