DEVELOPINGTHE MODEL OF THE MOTION OF A FLUID WITH VARIABLE DENSITY AND VISCOSITY IN THE DEVICE FOR DIVERSION OF DIFFUSION LAYER

Abstract

The research focuses on the process of exhausting the dense layers of fluid in a device for draining the diffusion layer. The paper studies the mathematical model for describing the motion of an incompressible fluid with variable viscosity and density. The proposed model is considered in a cylindrical coordinate system because of the characteristics of the computational domain. Also, the results of calculations are performed using the described model with constant viscosity and density. The resulting model can further be used for studying the process of removing the diffusion layer at concentrating milk using membrane filters.
