| Abstract: | In this paper a heat-flow coupling mathematic modeling about cascade flowing field and blade temperature field in turbomachinery is built. A program of 3-D heat conduct calculation in unorthogonal curve coordinates is developed, with this program heat distribution of a solid blade and a hollow blade is calculated. Domain decomposition method is introduced in coupling and parallel calculation, and the parallelization is studied in the example of calculating temperature distribution in rectangular zone. Finally coupling calculation about cascade flowing field and blade heat distribution is performed. |
