Abstract
Unsteady natural convection in a vertical cylindrical enclosure is numerically modeled in the case of heat input from above and from the side. The anisotropic effect of intense convection on the temperature field is established. It is shown that in the stratified region the temperature is well described by the time-dependent one-dimensional heat conduction equation with a three-dimensional heat source.
