NEUP CINR-23-29753: Immersed Boundary Methods for Modeling of Complex Geometry: A Leap Forward in Multiscale Modeling using NekRS

A major challenge to Computational Fluid Dynamics (CFD) modeling of complex geometries is the need to generate body-fitted meshes, which can occupy 80% of the CFD practitioner's time. We will add immersed boundary methods in the NekRS CFD code, dramatically simplifying modeling of complex 3-D structures and facilitating a new paradigm for CFD-informed multiscale analysis. We demonstrate by informing SAM transient systems-level models with NekRS heat exchanger correlations for advanced reactors.
