Web1 day ago · On a daily basis we stir tee or coffee with a spoon and leave it to rest. We know empirically the larger the stickiness, viscosity, of the fluid, more rapidly its velocity slows down. It is surprising, therefore, that the variation has not been utilized for measuring (dynamic) viscosity of fluids. This study shows that a spectroscopy decomposing a … WebApr 7, 2024 · Variational autoencoder (VAE) architectures have the potential to develop reduced-order models (ROMs) for chaotic fluid flows. We propose a method for learning compact and near-orthogonal ROMs using a combination of a $β$-VAE and a transformer, tested on numerical data from a two-dimensional viscous flow in both periodic and …

WebApr 21, 2024 · The difference between FVM and FEM is that the FVM discretizes the conservation form of PDEs while FEM discretizes the weak form of PDEs. FVM is a natural choice for CFD because the Navier-Stokes equations are really just conservation laws. FVM works by integrating the differential form of the equations over a control volume.
