Implicit LES with high-order H(div)-conforming FEM for incompressible Navier-Stokes flows (1809.06558v1)
Published 18 Sep 2018 in math.NA, physics.comp-ph, and physics.flu-dyn
Abstract: Consider the transient incompressible Navier-Stokes flow at high Reynolds numbers. A high-order H(div)-conforming FEM with pointwise divergence-free dis- crete velocities is applied to implicit large-eddy-simulation in two limit cases: i) decaying turbulence in periodic domains, ii) wall bounded channel flow.
