Unsteady temperature field of turbine disk analyzed by coupled boundary element-finite difference method
Abstract
The unsteady temperature field of a turbine disk is presently computed by means of the Brebbia et al. (1984) coupled boundary element finite-difference method, incorporating an additional boundary condition and occassionally incorporating a thermal-conductivity term. The application of the method to the calculation and analysis of the transient temperature field of a turbine disk is shown to require much less data and computing time, while yielding higher-accuracy results than the simple finite-element method.
