Abstract :
The present paper represents an attempt at a reasonably complete solution of the heat flow in large turbine generators, where the temperature drops through the various iron paths are of consequence. The solution of two-dimensional problems of heat flow is obtained by means of ``equivalent thermal circuits.´´ The approximations involved in this method are discussed in two appendixes where exact solutions are developed. The theory has been applied to a number of large turbine generators with satisfactory agreement between measured and calculated temperatures. The application of the results to actual machines will be made the subject of a subsequent paper.
