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

open access: yesThe 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

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.

Towards a Biodiversity Positive Business Strategy: The MCRV (Monitoring, Conserving, Restoring, Valorizing) Framework

open access: yesCorporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Despite mounting regulatory pressure and growing scientific consensus on biodiversity loss, most corporate action remains reactive, fragmented, and strategically peripheral. Existing frameworks address what firms should report rather than how they can build the organizational capabilities required to act strategically.

Performance assessment of a potential underground thermal storage facility: Case study of the closed mine Prosper‐Haniel in the Ruhr coal mining area in Germany

open access: yesDeep Underground Science and Engineering, EarlyView.
This study demonstrates the feasibility of an underground closed‐loop thermal storage facility at a post‐mining site, intended for seasonal heat energy storage. Its principal design shows water flow directions in winter and summer (1, 2), heat pumps (3), an upper water reservoir (4), and connecting pipes (5).

Seismic analysis and design of tunnels within fault ground: A review

open access: yesDeep Underground Science and Engineering, EarlyView.
The research methods of seismic response of tunnels within fault ground, including field investigations, analytical solutions, physical experiments, and numerical simulations, and seismic countermeasures are discussed. The present study examines the shortcomings and limitations of the current research and design, and puts forward proposals for future ...
