Evaluation of sub grid scale and local wall models in Large-eddy simulations of separated flow

E3S Web of Conferences, 2015
The performance of the Sub Grid Scale models is studied by simulating a separated flow over a wavy channel. The first and second order statistical moments of the resolved velocities obtained by using Large-Eddy simulations at different mesh resolutions ...

A New Method for Assessing Haemolysis in a Rotary Blood Pump Using Large Eddy Simulations (LES)

Chemical and Process Engineering, 2017
The opportunity to assess haemolysis in a designed artificial heart seems to be one of the most important stages in construction. We propose a new method for assessing haemolysis level in a rotary blood pump.

An Embedded Boundary Algorithm for Large Eddy Simulations in Complex Geometries [PDF]

INCAS Bulletin, 2012
The paper presents a novel implementation of the embedded boundary algorithm in a Large Eddy Simulation CFD algorithm. The embedded boundary method aims at allowing the simulation of complex geometry flows on Cartesian computational grids, increasing the

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

, 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.

Numerical Investigation of a Rectangular Jet Exhausting over a Flat Plate with Periodic Surface Deformations at the Trailing Edge

Aerospace, 2021
Multiple competing factors are forcing aircraft designers to reconsider the underwing engine pod configuration typically seen on most modern commercial aircraft. One notable concern is increasing environmental regulations on noise emitted by aircraft. In
