Large-Eddy Simulation of Contrails [PDF]
Journal 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 ...

Addressing Waste Disposal Fires in Open Fields Through Large Eddy Simulations
Chemical Engineering Transactions, 2021 Addressing fires in waste disposal facilities is of topical interest for firefighting and environmental protection. Statistics of fires that involve fuel matrixes made of diversified wastes are escalating and ask for an effective response, both in ...

Automated tracking of shallow cumulus clouds in large domain, long duration large eddy simulations [PDF]
Geoscientific Model Development, 2013 This paper presents a method for feature tracking of fields of shallow cumulus convection in large eddy simulations (LES) by connecting the projected cloud cover in space and time, and by accounting for splitting and merging of cloud objects.

Large eddy simulations in astrophysics [PDF]
Living 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.

Large eddy simulations of wind turbine wakes in typical complex topographies
Wind Energy, 2021 There is a need to clarify the coupling characteristics of terrain‐induced wind fields and wind turbine‐induced wake in wind farm micrositing. However, research investigating the effect of hill shape on this interaction is lacking.

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.
