DETERMINATION OF THE TEMPERATURE FIELD AND THERMAL STRESSES OF TURBINE DISCS
Abstract
A simplified method is given for calculating the temperature fields and the thermal stresses in radially cooled turbine discs. The method is based on results of investigations and studies conducted by the author in the Heat Engine Laboratory of the Institute of Heat and Power Engineering of the Academy of Sciences of the Ukrainian SSR and investigations of the temperature fields of rotors published in the Soviet Union and abroad. The material in the book is divided into three parts. The first part presented the simplified method and the sequence in the calculation of temperature fields and thermal stresses in turbine discs during the starting and the operational regimes of the turbine; it describes the use of the theory of a regular thermal regime to investigate heattransfer processes when stopping and starting a hot turbine. In the second part the method and the results are given of an experimental determination of temperature fields during the starting regimes in rotating full-scale discs of gas turbines. In the third part the influence of various factors on the temperature field of the cooling turbine disc and the basis, in this regard, of certain assumptions used when developing the simplified method are presented.
