gas between the cylinders). At = 2.0, Re = 100, heat exchange corresponds to the
heat exchange mode for the plane Couette flow. With an increase in the Reynolds
number, two-dimensional heat waves At = 1.0, Re = 100, the Couette flow mode
is formed, and then the heat exchange is determined at 200 < Re < 500 by plane heat
waves. A decrease in the rotation speed of the outer cylinder leads to a decrease in
the Re number, at which these waves are formed and in addition slightly increases
the heat flow. At = 1.0, Re > 600, as well as at = 0, the presence of the
Taylor vortices, whose formation implements the maximum value of Q, influences
the heat flow. In this case, the value of the heat flow is almost proportional to the Re
number (with the exception of the Re ≈ 100 area, when the Taylor vortices have just
formed). At Re = 1000, the heat exchange in the formation of the Taylor vortices in
