Abstract:

In studying the problem of thermal fields in structural installations it was found that when solving this problem the effect of thermal conductivity changes of the material can be disregarded. Described is a method based on gradual analog approximations, which enable a substantial simplification of the mathematical chalenging exercise, on how to determine the thermal field with consideration of changes in thermal conductivity with the rising temperature of the material. A concrete example shows how such effect may appear in a cooled turbine blade. Author
