Effects of surface roughness on molecular gas lubrication (Direct simulation Monte-Carlo analysis for shear flow)

Nihon Kikai Gakkai ronbunshu, 2020
Molecular gas film lubrication (MGL) equation, which is derived based on linearized Boltzmann equation, is the reliable means to analyze the molecular gas flow in the narrow channel, whose thickness is as thin as the molecular mean free pass. Though, the

Micro/Nanoscale Acoustic Manipulation: From Particle Control to Autonomous Microswimmers

Advanced Science, Volume 13, Issue 55, 5 October 2026.
This conceptual framework illustrates acoustic technology as a multifunctional platform enabling passive particle manipulation across scales and autonomous propulsion of microswimmers. ABSTRACT Acoustic manipulation and propulsion technologies have emerged as powerful platforms for micro/nanoscale control, enabled by their non‐contact operation, label ...

Solid particles focusing, orienting, and de‐focusing in planar Poiseuille flow

AIChE Journal, Volume 72, Issue 10, October 2026.
Abstract Three‐dimensional, time‐dependent lattice‐Boltzmann simulations of neutrally buoyant particles in planar Poiseuille flow have been performed. The particles are spherical or cylindrical (the latter with a length over diameter ratios in the range 1/3 to 2) and have volume fraction ranging from virtually zero (one particle) to 0.15. The channel's

Gas–liquid mass transfer enhancement in the presence of nanoparticles under slug flow in microreactors

AIChE Journal, Volume 72, Issue 10, October 2026.
Abstract Nanofluids containing nanoparticles represent a promising solvent or reaction system for gas–liquid operations. Herein, the effect of nanoparticle (Al2O3 and SiO2) addition on gas–liquid slug flow pattern and mass transfer enhancement was investigated during CO2 absorption into water in microreactors.

UniNS: A Neuro‐Symbolic Framework for Structure‐Regularized Causal Modeling of Catalytic Nanorobot Swarms in Confined Tumor Microenvironments

Applied Research, Volume 5, Issue 5, October 2026.
UniNS is a hybrid neuro‐symbolic framework that simulates nanoscale swarms in tumor microenvironments by coupling mesoscopic hydrodynamics with structure‐regularized causal discovery. It reduces biochemical prediction errors by 27.3% and dynamically prevents spurious correlations, offering a scalable, thermodynamically consistent testbed for precision ...

Air cushioning with a lubrication/ inviscid balance [PDF]

, 2003
The air cushioning effect in the gap between an almost inviscid body of water and a nearby solid wall (or another body of water) is studied theoretically and is found to depend on predominantly lubricating forces in the air, in certain applications.

Physics-informed neural network for hydrodynamic lubrication with film thickness discontinuity

Friction
Recent advancements in physics-informed neural networks (PINNs) have shown promise in solving partial differential equations (PDEs), including those in hydrodynamic lubrication. However, PINNs struggle with film thickness discontinuities because of their

Monolithic Framework to Simulate Fluid‐Structure Interaction Problems Using Geometric Volume‐of‐Fluid Method

International Journal for Numerical Methods in Fluids, Volume 98, Issue 10, Page 1105-1125, October 2026.
A three‐dimensional fluid‐structure interaction (FSI) framework is developed using the geometric volume‐of‐fluid (VOF) interface capturing method and applied to assess largescale turbulent FSI interactions. The monolithic FSI framework is extensively validated, and despite the discontinuities across the interface, the FSI framework delivers stable and ...
