In order to improve the accuracy and computing time of the numerical simulation for a heat transfer problem where the rate of temperature change is extremely high, the authors have developed a unique method which is proposed in this paper. The method, for a non-steady heat transfer equation, has a distinctive feature that two fundamental equations on the heat transfer phenomena, that is, q=-λgradθ, and (∂θ)/(∂t)=-1/(pc) div q are utilized respectively in computation. In this way, it mainly becomes much easier to determine the increment time of computing cycle, ⊿t which considerably affects to the accuracy as well as computing time of the numerical simulation. The detail of the method and discussion on results of some simulations are described here.
