Implicit LES with high-order H(div)-conforming FEM for incompressible Navier-Stokes flows
It provides a novel numerical method for implicit LES, targeting computational fluid dynamics researchers needing accurate, divergence-free solutions for turbulent flows.
The paper applies high-order H(div)-conforming FEM with pointwise divergence-free velocities to implicit LES for incompressible Navier-Stokes flows, demonstrating accuracy in decaying turbulence and wall-bounded channel flow at high Reynolds numbers.
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.
