Large–Eddy simulation of pulsatile blood flow [PDF]

open access: yesMedical Engineering & Physics, 2008
Large-Eddy simulation (LES) is performed to study pulsatile blood flow through a 3D model of arterial stenosis. The model is chosen as a simple channel with a biological type stenosis formed on the top wall. A sinusoidal non-additive type pulsation is assumed at the inlet of the model to generate time dependent oscillating flow in the channel and the ...

Gyrokinetic large eddy simulations [PDF]

open access: yesPhysics of Plasmas, 2011
The large eddy simulation approach is adapted to the study of plasma microturbulence in a fully three-dimensional gyrokinetic system. Ion temperature gradient driven turbulence is studied with the GENE code for both a standard resolution and a reduced resolution with a model for the sub-grid scale turbulence. A simple dissipative model for representing

Applied large eddy simulation [PDF]

open access: yesPhilosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2009
Large eddy simulation (LES) is now seen more and more as a viable alternative to current industrial practice, usually based on problem-specific Reynolds-averaged Navier–Stokes (RANS) methods. Access to detailed flow physics is attractive to industry, especially in an environment in which computer modelling is bound to play an ever increasing role ...

Comparison of Subgrid-scale Viscosity Models and Selective Filtering Strategy for Large-eddy Simulations [PDF]

open access: yes, 2013
Explicitly filtered large-eddy simulations (LES), combining high-accuracy schemes with the use of a selective filtering without adding an explicit subgrid-scales (SGS) model, are carried out for the Taylor-Green-vortex and the supersonic-boundary-layer ...

Localization of unresolved regions in the selective large-eddy simulation of hypersonic jets [PDF]

open access: yes, 2010
A method for the localization of the regions where the turbulent fluctuations are unresolved is applied to the selective large-eddy simulation (LES) of a compressible turbulent jet of Mach number equal to 5.

Large eddy simulation using high-resolution and high-order methods [PDF]

open access: yes, 2009
Restrictions on computing power make direct numerical simulation too expensive for complex flows; thus, the development of accurate large eddy simulation (LES) methods, which are industrially applicable and efficient, is required.

Large-eddy simulation of turbulent flow over a rough surface [PDF]

open access: yes, 2004
A family of wall models is proposed that exhibits more satisfactory performance than previous models for the large-eddy simulation (LES) of the turbulent boundary layer over a rough surface.The time and horizontally averaged statistics such as mean ...

Large eddy simulations in astrophysics [PDF]

open access: yesLiving Reviews in Computational Astrophysics, 2015
Abstract In this review, the methodology of large eddy simulations (LES) is introduced and applications in astrophysics are discussed. As theoretical framework, the scale decomposition of the dynamical equations for compressible neutral fluids by means of spatial filtering is explained.
