Abstract

In this paper, we report the use of medial axes transformation technique to predict temperature profile and hot spots in solidifying castings. In essence,we proposed a very simplistic yet comprehensive temperature interpolation algorithm which can solve the solidification problem qualitative and quantitatively.The method has the advantages of both the geometric reasoning technique and the conventional numerical simulation. We illustrate the feasibility of the proposed temperature interpolation technique by comparing its solutions with both pure geometric reasoning technique and the finite element method.
