The phenomena of convection anomalous thermoviscous fluid flow

The hydrodynamics particularities of currents that occur under heat convection of fluid with anomalous thermoviscous in a closed square cavity are studied. Mathematical model is based on the dynamics of continuous medium equation in the Oberbeck-Boussinesq approximation with nonmonotonic viscosity dependence of temperature. The finite volume method and SIMPLE algorithm based on multiprocessor technology are used for simulations. The dependence of anomalies parameters on the liquids convective flow character is considered. The influence of “viscous barrier” on the flows structure is determined for a number of problems variables.
