Total-Lagrangian vectorial lattice Boltzmann method for finite-strain hyperelasticity with curved boundaries
Jingsen Feng, Xu Chu
Finite-strain hyperelasticity on curved embedded domains poses a geometric challenge for lattice Boltzmann methods. After streaming across an embedded material surface, the missing…
A total-Lagrangian vectorial lattice Boltzmann method for finite-strain hyperelastic dynamics
Jingsen Feng, Xu Chu
Inspired by the vectorial lattice Boltzmann method for linear elastodynamics \citep{boolakee2025linear}, we construct a total-Lagrangian vectorial lattice Boltzmann formulation for…
Transient and asymptotic Taylor--Aris dispersion of Brownian rods in arbitrary regular-polygonal ducts
Jingsen Feng, Xu Chu
Taylor--Aris dispersion of Brownian rods in non-circular ducts is governed by a coupling absent from passive-scalar theory. Pressure-driven shear aligns the rods and makes translat…
Shear alignment and tensorial Taylor--Aris dispersion of Brownian rods in a circular tube
Jingsen Feng, Xu Chu
Brownian rods disperse in pressure-driven flow through a coupling between axial shear, anisotropic translational diffusion and Jeffery--Brownian rotation. Classical tube Taylor--Ar…
Entropic lattice Boltzmann method for general anisotropic advection--diffusion
Jingsen Feng, Jing Leng, Jingchao Jiang +1
Many transport processes exhibit direction-dependent diffusion, described macroscopically by the full-tensor anisotropic advection--diffusion equation (ADE). Numerical discretizati…
Engineering.ai: A Platform for Teams of AI Engineers in Computational Design
Ran Xu, Yupeng Qi, Jingsen Feng +1
In modern engineering practice, human engineers collaborate in specialized teams to design complex products, with each expert completing their respective tasks while communicating…
