A Self-Adaptive Strategy for the Time Integration of Navier-Stokes Equations
F. X. Trias,Oriol Lehmkuhl +1 more
TL;DR: An efficient self-adaptive strategy for the explicit time integration of Navier-Stokes equations is presented, which works independently of the underlying spatial mesh and can be easily integrated into structured or unstructured codes.
Journal ArticleDOI
Direct numerical simulation of the flow over a sphere at Re = 3700
TL;DR: The direct numerical simulation of the flow over a sphere is performed to provide reliable data for testing and developing statistical turbulence models, and the capability of the methodology used on unstructured grids for accurately solving flows in complex geometries is pointed out.
Journal ArticleDOI
Low-frequency unsteadiness in the vortex formation region of a circular cylinder
TL;DR: In this article, the flow dynamics of the near wake region behind a circular cylinder has been investigated by means of direct numerical simulations and statistics have been computed for more than 858 shedding cycles.
Book ChapterDOI
TermoFluids: A new Parallel unstructured CFD code for the simulation of turbulent industrial problems on low cost PC Cluster
TL;DR: The more relevant aspects from a parallel computing point of view, such as communication between CPUs and parallel direct and iterative algebraic solvers that allow TermoFluids to run efficiently on looselycoupled parallel computers are presented.
Journal ArticleDOI
Symmetry-preserving discretization of Navier-Stokes equations on collocated unstructured grids
TL;DR: A novel approach to eliminate the checkerboard spurious modes without introducing any non-physical dissipation is proposed, and a fully-conservative regularization of the convective term is used.
