Abstract
A method has been developed for the representation of the abstraction of heat from castings into bonded sand molds. The method consists of representing the local surface geometry by a plane, cylinder or sphere, based on the local heat flow environment. The characteristics of the heat flow into the mold for that surface shape are used to specify a set of boundary conditions on the casting.
The technique has been implements in an existing finite element method program to compute heat flow in solidifying castings. An example is included, with results compared to experiments.
