Consideration is given to a numerical determination 
of a two-dimensional unsteady viscous flow with the free surface in 
a stationarily rotating horizontal cylinder in which heat-exchange 
processes are carried out. The "marker-and-cell" method in a polar 
coordinate system is used. The features of modeling of the wall-layer 
regime and the circulating flow regime that occur in rapid and slow 
rotation of the cylinder, respectively, are discussed. Based on the 
given results of numerical calculations, the influence of the Reynolds 
number on the character of flow is analyzed.
