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

open access: yesChemie 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

open access: yesChemie 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

open access: yesThe 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.

A Geometric Characterization of Steady Laminar Flow

open access: yesCommunications 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.

Efficiency and Perceptions in Public CSR: An Integrated Efficiency–Perception Analysis of Spanish Defence Delegations

open access: yesCorporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Public organisations often experience a discrepancy between improvements in technical efficiency and stakeholders' perceptions of integrity and performance. This study analyses the mechanisms that may underlie this efficiency–perception discrepancy in Spanish Defence Delegations during 2020–2023.
