Karl Popper and the Mechanisms of Hydrogen Embrittlement

Advanced Engineering Materials, EarlyView.
Representation of the beginning of loss of ductility rather than embrittlement. Small concentrations of hydrogen in a diffusible form within iron are well‐established to harm the mechanical integrity of steels. There are theories that attempt to explain the pernicious role of hydrogen.

A Lattice Boltzmann model for multi-component vapor-liquid two phase flow

Petroleum Exploration and Development, 2014
In traditional multi-phase multi-component Lattice Boltzmann (LB) models, the phase properties especially the vapor-liquid equilibrium calculations failed to model the actual flow realistically.

Numerical simulation of duct flow in the presence of participating media radiation with total energy based entropic lattice Boltzmann method

International Journal of Thermofluids, 2023
Consideration of the effect of participating media radiation becomes essential for industrial systems due to the increasing use of high temperature materials. Participating media radiation is present in these systems with all other modes of heat transfer.

Toward Knowledge‐Based Workflows: A Semantic Approach to Atomistic Simulations for Mechanical and Thermodynamic Properties

Advanced Engineering Materials, EarlyView.
Knowledge‐based atomistic workflows are presented for mechanical and thermodynamic properties. By coupling modular simulations with ontology‐aligned metadata and provenance, Fe case studies on elastic behavior, defects, thermal properties, and Hall–Petch strengthening reveal how FAIR, queryable, and reusable simulation data can be generated.

Modeling multiphase flow with a hybrid model based on the Pore-network and the lattice Boltzmann method [PDF]

E3S Web of Conferences, 2020
Lattice Boltzmann method (LBM) simulations provide an excellent description of two-phase flow through porous media. However, such simulations require a significant computation time.

Inverse Identification of Energy‐Dependent Laser Absorptivity in NiTi Laser Powder‐Bed Fusion via Calibrated Melt Pool Simulation

Advanced Engineering Materials, EarlyView.
A combined experimental–computational framework identifies energy‐dependent laser absorptivity for NiTi in laser powder‐bed fusion, applicable to conduction and transition modes. Single‐track experiments and thermofluid smoothed particle hydrodynamics simulations are coupled through inverse analysis of melt pool geometry.

Enhanced Terahertz Thermoelectricity Via Engineered Van Hove Singularities and Nernst Effect in Moiré Superlattices

Advanced Functional Materials, EarlyView.
Moiré band engineering in graphene/hexagonal boron nitride–based superlattices unlocks van Hove singularities (VHSs) for terahertz (THz) optoelectronics. Tuning the Fermi level near these singularities, associated with secondary neutrality points (SNPs), enhances the photothermoelectric response.

Integrable 3D lattice model in M-theory

Journal of High Energy Physics, 2023
It is argued that the supersymmetric index of a certain system of branes in M-theory is equal to the partition function of an integrable three-dimensional lattice model.

The Lattice Boltzmann equation for modelling arterial flows : review and application

, 2003
The lattice Boltzmann model (LBM) is a relatively new development in computational fluid dynamics. Here we review the technique with particular emphasis on its application to biological systems.
