Simulation the motion of a viscous fluid containing graphene plates in the gap between static and rotating stepped discs

Abstract

The motion of a viscous fluid containing graphene nanostructures in a thin gap between a stationary stepped stator and a rotating stepped rotor is considered. Dependences are obtained for calculating the parameters of motion of an elementary volume of a viscous liquid. Using the Maple mathematical package, characteristic trajectories of movement of elementary volumes of fluid in the gap are obtained. A similar idea of the movement trajectories of an elementary volume was obtained using computational fluid dynamics using the Flow Vision package (TESIS, Russia). The transition from a mathematical description to a computer model makes it possible to take into account changes in the viscosity of a liquid caused by a change in the concentration of graphite in the initial suspension. The use of a computer model opens the way to modeling the mixing of graphene nanostructures with a viscous liquid.
