Modeling of Degassing of Viscoplastic Liquids in a Cylindrical Hydrocyclone

A mathematical model of degassing of viscoplastic liquids in a cylindrical hydrocyclone, taking into account the action of inertia forces and Coriolis forces and the liquid weight added was developed. The system of differential equations in partial derivatives, describing the gasification process, was reduced to a system of common differential equations and was solved by the numerical method. Based on the mathematical model developed, the influence exerted on the degree of removal of gas bubbles by the plasticity number at different values of the separation factor and nonlinearity parameter of the flow curve was analyzed. The results obtained were substantiated physically. They can be used in the development of the equipment for the treatment of drilling fluids and for the oil degassing prior to transportation.
