Abstract
This paper shows the development and the application of the fast calculation method of view factors using computer graphics (CG) images. This method uses the perspective images made by CG technique in order to calculate view factors that are necessary in heat transfer problems. The process to illustrate the perspective images by CG corresponds to searching planes with numerical calculation method such as Monte Carlo method. We showed view factors could be calculated at high speed by using graphics hardware. It was found that the accuracy of this method using CG technique was within the acceptable limit. We applied PPM to the rolling mill factory model only to perform the thermal environment assessment. It was verified that this method has a possibility to become an effective tool for the analysis of heat transfer problems with heat radiation.
