Large-Scale Cluster Parallel Strategy for Regularized Lattice Boltzmann Method with Sub-Grid Scale Model in Large Eddy Simulation

Applied Sciences, 2023
As an improved method of the lattice Boltzmann method (LBM), the regularized lattice Boltzmann method (RLBM) has been widely used to simulate fluid flow. For solving high Reynolds number problems, large eddy simulation (LES) and RLBM can be combined. The

Neural Fields for Highly Accelerated 2D Cine Phase Contrast MRI

Advanced Science, EarlyView.
ABSTRACT 2D cine phase contrast (CPC) MRI provides quantitative information on blood velocity and flow within the human vasculature. However, data acquisition is time‐consuming, motivating the reconstruction of the velocity field from undersampled measurements to reduce scan times. In this work, neural fields are proposed as a continuous spatiotemporal

Grid-transferable learning-based scheme for interface normal prediction from the volume fraction field on non-uniform Cartesian meshes

Engineering Applications of Computational Fluid Mechanics
Accurate estimation of interface orientation is critical for the performance of Volume of Fluid (VOF) methods in multiphase flow simulations, particularly on non-uniform Cartesian grids.

Eternal Domination: D-Dimensional Cartesian and Strong Grids and Everything in Between

, 2021
International audienceIn the eternal domination game played on graphs, an attacker attacks a vertex at each turn and a team of guards must move a guard to the attacked vertex to defend it. The guards may only move to adjacent vertices on their turn.

Traction Force Microscopy for Viscoelastic Substrates: A Semi‐Analytical Method

Advanced Science, EarlyView.
A semi‐analytical viscoelastic traction force microscopy framework is introduced for quantifying time‐resolved cell tractions on flat finite‐thickness substrates. The method generalizes elastic traction force microscopy to Generalized Maxwell materials, identifies when elastic approximations remain valid and, when they do not, shows that inferred ...

Synthetic Turbulence Generation for LES on Unstructured Cartesian Grids [PDF]

, 2007
A parallel CFD code to solve incompressible fluid flow on unstructured Cartesian meshes has been developed almost from ground up. Turbulence statistics have been computed using the Large Eddy Simulation technique.

Synergistic Spin‐Polarization and Single‐Atom Engineering in Magnetic Heterojunctions for Efficient Solar Water Splitting

Advanced Science, EarlyView.
High‐throughput screening led to the identification of 67 Z‐scheme heterojunctions (comprising 2D magnetic transition metal halides and non‐magnetic transition metal chalcogenides). For CrI3/MoTe2 and CrI3/WTe2, electronic structure analysis demonstrated that synergistic crystallographic point group and built‐in electric field effects generate a ...

Oriented Chromatic Number of Cartesian Products and Strong Products of Paths

Discussiones Mathematicae Graph Theory, 2019
An oriented coloring of an oriented graph G is a homomorphism from G to H such that H is without selfloops and arcs in opposite directions. We shall say that H is a coloring graph.

Domination criticality in product graphs

AKCE International Journal of Graphs and Combinatorics, 2015
A connected dominating set is an important notion and has many applications in routing and management of networks. Graph products have turned out to be a good model of interconnection networks. This motivated us to study the Cartesian product of graphs G

A Computational Model on Cartesian Adaptive Grid for Thrombosis Simulation

IEEE Access, 2022
Computer simulation has been an effective experimental method to study the mechanism of thrombosis. As a computational model is the core of the simulation, a hybrid computational model which focuses on improving the modelling of thrombus growth is proposed in this paper.
