Large-Eddy Simulation of Contrails [PDF]

open access: yesJournal of the Atmospheric Sciences, 1998
Numerical simulations of contrails have been performed to investigate the role of various external parameters and physical processes in the life cycle of contrails. The general idea underlying the model is that of a largeeddy model. The model explicitly represents the large-scale three-dimensional motions (10-m grid resolution), while small-scale ...

Study on lattice Boltzmann method/large eddy simulation and its application at high Reynolds number flow

open access: yesAdvances in Mechanical Engineering, 2015
Lattice Boltzmann method combined with large eddy simulation is developed in the article to simulate fluid flow at high Reynolds numbers. A subgrid model is used as a large eddy simulation model in the numerical simulation for high Reynolds flow.

Large-Eddy simulation of pulsatile blood flow [PDF]

open access: yes, 2009
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.

Application of Large Eddy Simulation in the process of the Multi-Physics Field Coupling in a Combustion Chamber

open access: yesMATEC Web of Conferences, 2015
Numerical simulation is the main method to solve turbulence problems. As one of the three methods which are commonly used in large-eddy simulation model (LES) is the most effective and promising research method. The basic idea of large-eddy simulation is

Pressure fluctuation prediction in pump mode using large eddy simulation and unsteady Reynolds-averaged Navier–Stokes in a pump–turbine

open access: yesAdvances in Mechanical Engineering, 2016
For pump–turbines, most of the instabilities couple with high-level pressure fluctuations, which are harmful to pump–turbines, even the whole units. In order to understand the causes of pressure fluctuations and reduce their amplitudes, proper numerical ...
