Abstract
Predicting the misruns in thin-wall castings is required to produce lightweight high performance components. A general 1D heat transfer model for predicting the heat extraction of thin-wall castings is proposed. Temperature dependent properties calculated from a thermodynamic database are used to incorporate latent heat. A stopping criterion, related to a critical solid fraction, has been introduced to determine when the fluid solidifies and obstructs the flow. The model has been used to predict cast lengths in several conditions found in literature including die casting, sand casting and Ragone tests with good agreement to reported lengths. This model shows potential for use in 3D simulations of thin-wall castings.
