Convective Flows of Anomalous Thermoviscous Fluid

Resumo

The specific hydrodynamic properties of flows occurring under the heat convection of fluid with anomalous thermoviscosity in a closed square cavity are studied. The mathematical model is based on the equations of the dynamics of a continuous medium in the Oberbeck-Boussinesq approximation with a nonmonotonic viscosity dependence of the temperature. The finite volume method and SIMPLE algorithm based on multiprocessor technology are used for simulation. The dependence of the anomaly parameters on the character of the convective flow of the liquid is considered. The influence of the viscous barrier on the flow structure is determined for a number of problem parameters.
