Turbulent heat transfer in a freely rotating disk with 
an arbitrary change in the wall temperature is investigated. With 
the aid of the integral method developed previously, numerical simulation 
for the cases of positive, approximately constant, and negative radial 
temperature gradients of the disk is carried out. Unlike the known 
Dorfman method, the results of the calculations performed agree well 
with experimental data. Based on the data obtained, conclusions are 
drawn about relatively optimum parameters of the model for the conditions 
under consideration.
