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.

Innovation and Growth Investment Through Capital Expenditure as a Channel and Boundary Condition Between Financial Performance and Corporate Reputation

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT This study examines the role of capital expenditure in the relationship between financial performance and corporate reputation. Using moderation and mediation analyses based on multiple regressions with bootstrapping, we examined data from 121 airlines from 46 countries during 2007–2023.

Is It Possible to Create Financial Value Through Sustainability Strategies in Asset Management? The View of Occupational Pension Funds

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT This paper examines whether occupational pension funds (OPFs) apply a strategic and long‐term logic when assessing ESG practices in their investee firms. Using discourse analysis of semi‐structured interviews with asset managers and workers' representatives, we examine whether Spanish OPFs look beyond compliance‐driven CSR and consider the ...

The Interplay of ESG Performance and Global Supply Chains: An Input–Output Study of China, Japan, and the United States

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT This study examines how supply‐chain dependencies are associated with industry‐level ESG performance trajectories in China, Japan, and the United States over the period 2000–2021. Drawing on stakeholder and institutional theories, we adopt a meso‐level perspective that conceptualizes industries as structural units embedded within national ...
