Stability analysis of the vectorial Lattice-Boltzmann method [PDF]

ESAIM: Proceedings and Surveys
We perform a stability analysis of the Vectorial Lattice-Boltzmann Method (VLBM). The VLBM has been introduced in [1–3, 9, 18]. It is a variant of the LBM with extended stability features: it allows handling compressible flows with shock waves, while the

An explicit power-law-based wall model for lattice Boltzmann method–Reynolds-averaged numerical simulations of the flow around airfoils

The Physics of Fluids, 2018
In this paper, an explicit wall model based on a power-law velocity profile is proposed for the simulation of the incompressible flow around airfoils at high Reynolds numbers.

Reactive Carbide‐Based Synthesis and Microstructure of NASICON Sodium Metal All Solid‐State Electrolyte

Advanced Materials, EarlyView.
Sodium Metal All‐Solid State Batteries (Na‐ASSBs) are enabled by the synthesis of the solid state electrolyte, NASICON (Na1+xZr2SixP3‐xO12), using carbide‐based precursor compounds (ZrC and SiC); resulting in dense, pure, and mechanically improved microstructure.

Energy-Efficient Implementation of the Lattice Boltzmann Method

Energies
Energy costs are now one of the leading criteria when procuring new computing hardware. Until recently, developers and users focused only on pure performance in terms of time-to-solution.

Electrically Assisted Thermal Stamping of Tunable Carbon‐Based Nanofilms for Direct Fabrication of Hydrophobic, Energy Harvesting, and Sensing Devices

Advanced Materials, EarlyView.
Schematic illustration of the electrically assisted thermal stamping (EATS) method for direct fabrication of carbon‐based nanofilms and their multifunctional applications. Localized Joule heating triggers simultaneous exfoliation, reduction, and fluoropolymer incorporation under ambient conditions, yielding tunable carbon‐based thin‐film coatings ...

Polarize the Solvent to Regulate the Intermediate Phase and Dynamic Crystallization of Perovskite Films

Advanced Materials, EarlyView.
A solvent engineering strategy using polar polymers is introduced to regulate perovskite crystallization dynamics in solar cells. Strongly polarized fluorinated groups stabilize the intermediate phase and control solvent exfoliation, leading to high‐quality films with suppressed defects.

Zynq SoC based acceleration of the lattice Boltzmann method

Concurrency and Computation, 2019
Cerebral aneurysm is a life‐threatening condition. It is a weakness in a blood vessel that may enlarge and bleed into the surrounding area. In order to understand the surrounding environmental conditions during the interventions or surgical procedures, a
