Evaluation of temperature wall functions for large-eddy simulation over curvilinear geometries

Recently, a novel transport scheme combining a cut-cell finite volume method for scalars and a direct-forcing immersed boundary method for momentum has been implemented in the open-source, low-Mach LES solver called the Fire Dynamics Simulator (FDS). This talk discusses the implementation and testing of heat transfer wall functions over curvilinear and non-grid-aligned geometries. Nusselt number correlations are compared for forced and natural convection.
