The Modelling of Fluid Flow Phenomena in Foundry Operations
An overview is given of fluid flow phenomena in foundry operations. It is shown that fluid flow phenomena play a key role in affecting the kinetics of many physicochemical processes in foundry systems associated with the production, refining and casting of foundry iron.
A general methodology is described for formulating problems of this type, with emphasis on the numerous problems that may now be quite accurately addressed with the aid of mathematical modeling.
The examples cited include the behavior of gas bubble stirred ladles, thermal stratification of melts held in ladles, induction furnaces and a simplified case of mold filling. In all these cases the theoretical predictions were found to be in good agreement with experimental measurements.
