The effect of a radial change in the wall temperature 
on heat transfer in centrifugal turbulent flow in a gap between parallel 
rotating disks is investigated. Cases of positive, approximately constant, 
and negative radial gradients of the disk temperature are considered. 
The results of calculating by the integral method are in good agreement 
with the known experiments. It is shown that the change in the wall 
temperature has an insignificant effect in the region of the source 
and a determining effect in the Ekman layers, finally giving rise 
to a zone with return heat flux at the periphery of the cavity with 
negative and approximately constant gradients of the disk temperature.
