Unsteady natural convection regimes in tilted cylindrical enclosure with heat-conducting walls of finite thickness and heat source in the conditions of convective heat exchange with an environment are numerically analyzed. The mathematical simulation is based on solving three-dimensional convection equations under Boussinesq approximation in terms of dimensionless variables such as «vector potential-vorticity vector-temperature». The main attention is given to the analysis of the effects of the Prandtl and Rayleigh numbers, unsteady regimes, the thermal conductivity ratio and the inclination angle on the velocity and temperature fields.
