In work results of a numerical research of influence of viscosity-temperature relation on structure of a convective Couette flow of thermoviscous liquid are presented in ring area between two coaxial cylinders under a condition when one of them has more high temperature.
Comparison of a convective Couette flow of model liquid with non-monotone temperature dependence of viscosity and liquid with constant viscosity is carried out. Depending on parameters of viscosity anomaly the steady and oscillation flow regimes both with periodic and with not repeating fluctuations of vortex structures are found. The number of time-constant vortex structures also depends on parameters of viscosity anomaly.
