A novel method for computation of temperature profile of turbine disk

Abstract

A novel temperature computation method of turbine disk is proposed according to theoretical analysis, where the coupling analysis of the outer surface in disk and fluid relative to this outer surface was carried out, instead of the segregation condition (constant wall temperature or constant wall heat flux condition). The selected correlations, numerical and experimental data of the heat transfer coefficient are presented and compared, so are the theoretical and simulated temperature profiles. The results show that: The maximum temperature deviation coefficient (φ T ) between the theoretical results and simulation data is less than 8.7% while Re Φ = 4.
