Title
Numerical Analysis of Heat Transfer and Thermal Stresses in the Casting Process
이진호 , 목진호 Jin Ho Lee , Jin Ho Mok
Abstract
An attempt is made to see numerically the effect on the solidification of cooling during filling process and the residual flow after finishing filling process in a casting process. Emphasis is given to simultaneous analysis of fluid flow and heat transfer in the whole casting process from filling to the end of solidification. To treat the free surface, MAC method is employed in the SIMPLER algorithm of the finite volume approach. Thermal stresses during solidification is calculated based on temperature distributions through the finite element analysis. Results show the distinct difference between the present analysis and the conventional analysis, which just deals with solidification process only.
