Sažetak
For the solving of different problems in designing of new and exploitation of the existing steam and gas turbines it is necessary to perform the calculation of heat transfer on disc surfaces (i.e. on rotor surfaces) and for this the values of convective heat transfer coefficients have to be known. The latter are most frequently determined on the basis of correlations obtained by means of experimental measurements, often without checking the possibility of their application in the individual case. In literature, there is a definite number of empirical correlations proposed by various researchers, which are mutually distinguished with regard to the range of change of the geometrical and gas-dynamics parameters and with regard to choosing physical properties. All this makes their application more difficult. Therefore, in the paper, the systematisation of empirical correlations from literature is performed first, and after that the original generalised correlations are proposed obtained by means of statistical analysis of calculation results by systematised single correlations. The original generalised correlations proposed in the paper ensure accuracy of calculations which satisfy engineering applications.
