| Abstract: | The heat characteristics in the end region of turbogenerator is studied and the heat disspat-ing coefficients of various surfaces are obtained by means of analytical method.Three dimensionalmathematic model with considering cooling pipe for calculating the temperature field is established.Three dimensional temperature field is calculated by Finite Element Methed. The effect of temperaturedistribution from the structural design in the end region is discussed in detail.As an example,the tem-perature distribution in the end region of a type QFS- 300-2 turbogenerator is calculated.The resultsshow that the calculative method and theoretical analysis presented in this paper is correct and reliable. |
