A time-consistent stabilized finite element method for fluids with applications to hemodynamics
Published 2023-11-01“…Abstract Several finite element methods for simulating incompressible flows rely on the streamline upwind Petrov–Galerkin stabilization (SUPG) term, which is weighted by $$\tau _{\text{SUPG}}$$ τ SUPG . …”

Fluid mechanics in fluids at rest
Published 2012“…Rather, tracer-velocity equality holds only for incompressible flows. For compressible fluids, each type of tracer is shown to monitor a fundamentally different fluid velocity, with (i) a dye (or any other such molecular-tagging scheme) measuring the fluid's mass velocity v appearing in the continuity equation and (ii) a small, physicochemically and thermally inert, macroscopic (i.e., non-Brownian), solid particle measuring the fluid's volume velocity v[subscript v]. …”

Proposal of a critical test of the Navier-Stokes-Fourier paradigm for compressible fluid continua
Published 2013“…Independently of the correctness of the bivelocity model, any temperature difference observed during the proposed experiment or simulation, irrespective of magnitude, would preclude the possibility of the NSF paradigm being correct for fluid continua, except for incompressible flows.…”

Energy transfer and vortex structures: visualizing the incompressible turbulent energy cascade
Published 2023-01-01“…Here, we focus on incompressible flows and compare the energy transfer occurring in a statistically steady homogeneous isotropic turbulent (HIT) flow with the generation of fine-scale motions in configurations involving vortex tubes. …”

A Massively Parallel Hybrid Finite Volume/Finite Element Scheme for Computational Fluid Dynamics
Published 2021-09-01“…To show the versatility of the proposed schemes, we present a wide range of applications, starting from environmental and geophysical flows, such as dambreak problems and natural convection, over direct numerical simulations of turbulent incompressible flows to high Mach number compressible flows with shock waves. …”
