Fourier-Informed Knot Placement Schemes for B-Spline Approximation
David Lenz, Oana Marin, Vijay Mahadevan +2
Fitting B-splines to discrete data is especially challenging when the given data contain noise, jumps, or corners. Here, we describe how periodic data sets with these features can…
Direct Numerical Simulation of Fluid Flow in a 5x5 Square Rod Bundle Using Nek5000
Adam Kraus, Elia Merzari, Thomas Norddine +2
Rod bundle flows are commonplace in nuclear engineering, and are present in light water reactors (LWRs) as well as other more advanced concepts. Inhomogeneities in the bundle cross…
Towards Direct Numerical Simulation of a 5x5 Rod Bundle
Adam Kraus, Elia Merzari, Thomas Norddine +2
Rod bundle flows are prevalent in nuclear engineering for both light water reactors (LWR) and advanced reactor concepts. Unlike canonical channel flow, the flow in rod bundles pres…
Fourier Neural Networks as Function Approximators and Differential Equation Solvers
Marieme Ngom, Oana Marin
We present a Fourier neural network (FNN) that can be mapped directly to the Fourier decomposition. The choice of activation and loss function yields results that replicate a Fouri…
