Inverse modeling for large-eddy simulation [PDF]

Physics of Fluids, 1997
Approximate higher order polynomial inversion of the top-hat filter is developed with which the turbulent stress tensor in large-eddy simulation can be consistently represented using the filtered field. Generalized (mixed) similarity models are proposed which improved the agreement with the kinetic energy transfer to small scales.

Numerical simulation of flow separation over a backward-facing step with high Reynolds number

Water Science and Engineering, 2019
Large eddy simulation (LES) explicitly calculates the large-scale vortex field and parameterizes the small-scale vortices. In this study, LES and κ-ε models were developed for a specific geometrical configuration of backward-facing step (BFS).

Fully 3D‐Printed Wave‐Wound Electromagnetic Motors

Advanced Materials Technologies, EarlyView.
This work presents the first fully 3D‐printed wave‐wound electromagnetic motors, which are created using conductive nanoparticle inks, carbon‐filled nylon polymers, and surface mount components. These motors can achieve a stall torque of 7.62N·mmA−1$7.62 \nobreakspace N{\cdot }mm A^{-1}$ and efficiency of 28.2 %, which approaches the performance of ...

Large Eddy Simulation of Turbulent Channel Flows by the Rational LES Model

, 2002
The rational large eddy simulation (RLES) model is applied to turbulent channel flows. This approximate deconvolution model is based on a rational (subdiagonal Pade') approximation of the Fourier transform of the Gaussian filter and is proposed as an ...

β‐Triketone‐Based Ionizable Cationic Lipids Synthesized via Click Chemistry for siRNA Delivery

Advanced Science, EarlyView.
This study innovatively applies β‐triketone‐based click chemistry in the synthesis of ionizable cationic lipids (ICLs), which allows the generation of a lipid library in large quantities and in a short time. The ICLs identified achieved effective lipid nanoparticles‐mediated hepatic gene silencing in vivo using siRNA, and computational simulations are ...

Rain Evaporation, Snow Melt, and Entrainment at the Heart of Water Vapor Isotopic Variations in the Tropical Troposphere, According to Large‐Eddy Simulations and a Two‐Column Model

Journal of Advances in Modeling Earth Systems, 2021
We aim at developing a simple model as an interpretative framework for the water vapor isotopic variations in the tropical troposphere over the ocean. We use large‐eddy simulations of disorganized convection in radiative‐convective equilibrium to justify

A large eddy lattice Boltzmann simulation of magnetohydrodynamic turbulence

, 2017
Large eddy simulations (LES) of a lattice Boltzmann magnetohydrodynamic (LB-MHD) model are performed for the unstable magnetized Kelvin-Helmholtz jet instability. This algorithm is an extension of Ansumali et. al.
