Advanced Intelligent Systems, EarlyView.The space pump transports lunar regolith under vacuum condition. A fully 3D‐printed biomimetic peristaltic pump demonstrates reliable transport of liquids and solids using pneumatic ring actuators and flexible fused filament fabrication. The system operates under atmospheric and vacuum conditions, achieves high flow rates, and enables self‐priming ...

The Canadian Journal of Chemical Engineering, EarlyView.A perturbative Graetz model describes coupled heat and mass transfer in reactive Couette–Poiseuille flow between parallel plates. Viscous dissipation and heat of reaction produce a small temperature rise, which enhances Arrhenius reaction rates and modestly accelerates axial species conversion in the small‐Brinkman‐number regime.

A Study of Numerical Schemes for Incompressible Fluid Flows
Trends in Computational and Applied Mathematics, 2005 The present work is concerned with a study of numerical schemes for solving two-dimensional time-dependent incompressible free-surface fluid flow problems. The primitive variable flow equations are discretized by the finite difference method.

Polymer Engineering &Science, EarlyView.In the filament force measurement (FFM), the friction of the solid filament, determined in an open‐bore reference, is subtracted from the measured extrusion force to obtain the capillary force. The resulting apparent viscosity is compared with high‐pressure capillary rheometry (HPCR) using the identical printer nozzle in both instruments.

Multiscale Apparent Permeability Model of Shale Nanopores Based on Fractal Theory
Energies, 2019 Based on fractal geometry theory, the Hagen−Poiseuille law, and the Langmuir adsorption law, this paper established a mathematical model of gas flow in nano-pores of shale, and deduced a new shale apparent permeability model.

Sucrose solution viscosity determination on evaporator by Coriolis flow meter [PDF]
Journal on Processing and Energy in Agriculture, 2011 The scope of this paper is the determination of viscosity of sucrose solutions using the Coriolis flow meter. Previous research showed that the Coriolis flow meter can be successfully applied to determine the viscosity of water, where instead of the ...

Steady‐State and Dynamic Behavior of Geometry‐Tunable Microfluidic Passive Flow Regulators
Small, EarlyView.Passive microfluidic flow regulators exhibit geometry‐dependent dynamic behavior, where channel width governs the resistance–compliance interactions within the system. Narrow channels produce faster responses with higher bandwidth, while wider channels yield slower responses and stronger attenuation.
