Development of a 3D/1D Round Patched Transient Heat Transfer Model for Simulations of Heat Transfer through the Casting–Mold Interface

Abstract

In this article a 3D/1D round patched transient heat transfer model is proposed to further improve the 3D/1D model. In the 3D/1D model, when an angle is present in a geometric model, the effect of “dead corner” damages the accuracy of the calculation. In the 3D/1D round patched model, a round patch is used to fill the “dead corner” and overcome the effect of “dead corner.” The 3D/1D round patched model is integrated into the 3D CFD code PHYSICA. The simulation results show that the 3D/1D round patched model improves accuracy when calculating heat transfer through the mold–casting interface.
