Entropic lattice Boltzmann methods: A review

Computers & Fluids, 2023
في أواخر التسعينيات وأوائل عام 2000، كان مفهوم نظرية H المنفصلة ووظائف Lyapunov كوسيلة لضمان استقرار حلال بولتزمان المشابك تحولًا في النموذج في بناء حلالين حركيين منفصلين وفتح الباب أمام مناقشات ووجهات نظر جديدة حول هذه المسألة. اقترح البناء الإنتروبي إعادة تنظيم مشغل تصادم الاسترخاء عن طريق تغيير كل من جاذب التوازن وعملية الاسترخاء من خلال إدخال ...

Scalable Thermal Engineering via Femtosecond Laser‐Direct‐Written Phononic Nanostructures

Advanced Functional Materials, EarlyView.
This study demonstrates that femtosecond laser‐induced periodic surface structures (fs‐LIPSS) can function as phononic metasurfaces, reducing thermal conductivity below the plain thin‐film limit. Phonon Monte Carlo analysis reveals that the periodic structures restrict phonon mean free paths.

Stacking‐Engineered Magnonic Topology and Transport in Honeycomb Homobilayers

Advanced Functional Materials, EarlyView.
ABSTRACT Topological magnons have emerged as a promising platform for dissipationless bosonic transport. However, a straightforward and effective strategy to engineer such topological states in real materials has yet to be fully realized. Here, a general scheme for controlling magnonic topological states via stacking engineering in van der Waals ...

Active microrheology of fluids with orientational order

Condensed Matter Physics
We study the dynamics of a driven spherical colloidal particle moving in a fluid with a broken rotational symmetry. Using a nematic liquid crystal as a model, we demonstrate that when the applied force is not aligned along or perpendicular to the ...

Numerical study of particle capture efficiency in fibrous filter

EPJ Web of Conferences, 2017
Numerical simulations are performed for transport and deposition of particles over a fixed obstacle in a fluid flow. The effect of particle size and Stokes number on the particle capture efficiency is investigated using two methods.

Flow Simulation of Artificially Induced Microfractures Using Digital Rock and Lattice Boltzmann Methods

Energies, 2018
Microfractures have great significance in the study of reservoir development because they are an effective reserving space and main contributor to permeability in a large amount of reservoirs.

Detailed analysis of the lattice Boltzmann method on unstructured grids

, 2014
The lattice Boltzmann method has become a standard for efficiently solving problems in fluid dynamics. While unstructured grids allow for a more efficient geometrical representation of complex boundaries, the lattice Boltzmann methods is often ...

Implicit and explicit solvent models for the simulation of a single polymer chain in solution: Lattice Boltzmann vs Brownian dynamics [PDF]

, 2009
We present a comparative study of two computer simulation methods to obtain static and dynamic properties of dilute polymer solutions. The first approach is a recently established hybrid algorithm based upon dissipative coupling between Molecular ...
