A fast radiative heat transfer program is developed for the simulation of unidirectional precision casting of gas turbine blade. Calculation speed is increased by incorporating three new methods. View factors are calculated by introducing an approximation equation and simplified surface integral. The visibility at surface elements is judged by extended plane-sweep method. For radiosity calculation in the radiative heat transfer analysis, multiple reflection is neglected. As the result, the present algorithm reduces the computation time for a model with 700 elements from 300 sec to 4 sec within accuracy of 3%.
