Skin‐Interfaced Wearable Device for Synchronically Harvesting High‐Entropy Body Energy and Monitoring Deep Tissue Temperature

Carbon Energy, EarlyView.
A thermal meta‐design is utilized to geometrically confine naturally dispersed cutaneous heat into a guided vertical path, which facilitates synchronous deep tissue temperature monitoring and high‐entropy energy harvesting, thereby significantly enhancing thermoelectric conversion.

The Filament Extension Atomization Process for Powder Production of Elastic Fluids

Chemie Ingenieur Technik, EarlyView.
Filament extension atomization is a promising technique for spraying a wide range of materials, enabling narrow droplet size distributions. This study examines the behavior of various fluids and suspensions to define application limits and identify optimal operating conditions.

Integral Experiments and Magnetic Resonance Imaging of Lab‐Scale Liquid Distributors

Chemie Ingenieur Technik, EarlyView.
Four lab‐scale liquid distributors were evaluated based on the homogeneity of the resulting liquid distribution. The best‐performing design reduced maldistribution and wall flow compared to a single‐point liquid distribution and remained stable under varying operating conditions, including different gas and liquid loads.

Comparative Study of Gas and Liquid Flow in Packed Beds Using Phase‐Contrast MRI

Chemie Ingenieur Technik, EarlyView.
This work presents applications of phase‐contrast magnetic resonance imaging (MRI) to investigate fluid flow fields and temperature in packed beds. Comparison of ethane (C2H6) gas flow with that of water flow is done at similar flow conditions. The temperature of water is also measured using MRI.

Review of CFD modelling techniques for single‐phase and multiphase flow in static mixers

The Canadian Journal of Chemical Engineering, EarlyView.
This review synthesizes computational fluid dynamics (CFD) approaches for static mixers, linking hydrodynamics to pressure drop, particle/droplet distributions, mixing metrics, and heat‐transfer performance to guide modelling choices and design decisions. Abstract Static mixers enable compact and low‐energy intensification.

Algebraic model for predicting the hydrodynamics of cocurrent three‐phase fluidized columns

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract This study presents a novel simplified set of momentum equations to predict the overall hydrodynamics of a cocurrent gas–liquid–solid slurry bed, including phase fractions and pressure drop. The mentioned momentum closures are derived from an idealization of the upward flows within the bed of solid particles, obtained by extending an approach ...

Transient cooling and gelation of a waxy‐oil pipeline during shutdown: Effects of insulation and external convection

The Canadian Journal of Chemical Engineering, EarlyView.
Graphical overview of waxy‐oil solidification during pipeline shutdown under different external cooling and insulation conditions. Abstract Wax solidification during pipeline shutdown was investigated in this study using a 3D transient computational fluid dynamics (CFD) model incorporating conjugate heat transfer, temperature‐dependent thermophysical ...

A Geometric Characterization of Steady Laminar Flow

Communications on Pure and Applied Mathematics, EarlyView.
ABSTRACT We study the steady states of the Euler equations on the periodic channel or annulus. We show that if these flows are laminar (layered by closed non‐contractible streamlines which foliate the domain), then they must be either parallel or circular flows.
