Computational Modelling of Motion of High Molecular Compound (Hmc) Solution in Membrane Concentration Unit

Abstract

Waste free production of food raw material is a significant task in food industry. In order to solve this problem it is important to separate milk components to manufacture different foodstuff thereafter. One of the challenging means of milk separation is the application of membrane technologies that possess more advantages compared with traditional methods such as fractioning, absorption and extraction due to its cost-effectiveness and preserving native state of raw materials. It has to be noted that this separation technology demands boundary layer separation on the membrane surface with high protein concentration. A set of devices (concentrators) of different configurations for removal of wall layer has been presented. Their design characteristics can significantly influence the efficiency of concentration process. The paper has studied the concentration process of high molecular substance and the correspondence between concentration quality and input data based on the mathematical model of motion of two-component viscous incompressible fluid with variable density and viscosity.
