Abstract

The 3D/1D patched transient heat transfer model is further developed in this article to eliminate the effect of the "dead corner" for the 3D geometry. In the previous study, a patch is introduced in the "dead corner" to extend the calculation to the "dead corner". It was found that the 3D/1D patched transient heat transfer model does not function in a 3D geometrical model. In this study, a 3D patch is used to fill a "3D dead corner" and implemented into 1D transient heat transfer model. The coupling of 1D transient heat transfer model and 3D model has been integrated into the 3D CFD code PHYSICA. 1D transient heat transfer equation is computed via the FD solution of a 1D heat transfer equation in the structure while 3D turbulent fluid flow equations and 3D heat conservation equations are computed in the fluid. The 3D boundary temperature is updated during the 3D FV solution procedure by considering heat balance at the interface. The simulation results show that 3D/1D 3D-patched model improves the accuracy when calculating the heat transfer through the fluid-structure interface for a 3D geometry.
