In the paper, free convection of thermally viscous liquids in a square cell is numerically investigated. Quadratic and exponential viscosity versus temperature is considered. The influence of these dependences on the Nusselt number is studied. It is established that the dependence of the Nusselt number on the Rayleigh numbers is characterized by the average viscosity, monotonicity, and convexity of the viscosity function of temperature.
