三重相反境界要素法による三次元非定常熱伝導解析(熱工学,内燃機関,動力など)  [in Japanese] Three-Dimensional Unsteady Heat Conduction Analysis by Triple-Reciprocity Boundary Element Method(Thermal Engineering)  [in Japanese]

The conventional boundary element method (BEM) needs a domain integral in heat conduction analysis with heat generation or initial temperature distribution. This paper shows that the three-dimensional heat conduction problem can be solved effectively by using the triple-reciprocity boundary element method without internal cells. In this method, the distribution of heat generation and initial temperature are interpolated by using integral equations. In this method, time-dependant fundamental solutions are used. A new computer program was developed and applied to solving several problems.
