Heat stress relief by tidally driven cold‐water bores on a coral reef atoll

Limnology and Oceanography, Volume 71, Issue 4, April 2026.
Abstract Understanding how physical transport mechanisms influence coral reef temperature dynamics is crucial for effective management. Typically, sea surface temperature (SST) is used to estimate coral heat stress, yet subsurface physical processes can significantly influence reef temperature dynamics and are imperative to consider in predictive ...

Modeling Liquid‐Mediated Interactions for Close‐to‐Substrate Magnetic Microparticle Transport in Dynamic Magnetic Field Landscapes

Particle &Particle Systems Characterization, Volume 43, Issue 4, April 2026.
The trajectory of a single magnetic particle moving close to a polymer surface in a tailored magnetic field landscape surrounded by a static fluid is quantified using an adjustable simulation model. Varying simulation parameters give insights in key properties of magnetic particle‐based Lab‐on‐a‐chip systems for medical diagnostics.

Calibrated Granular‐Flow PIV From DEM Simulations: Flow‐Substrate Dynamics in Flows With Fixed and Erodible Substrates, Modeling, and Field Implications

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 4, April 2026.
Abstract Granular flows are central to geophysical and industrial processes, yet their internal properties remain difficult to quantify. Understanding how energy and momentum are exchanged at the flow–substrate boundary is key to predicting their erosion and mobility.

Experimental Investigation of Microbubble Evolution in the Liquivac Multiphase Flow Pump

Asia-Pacific Journal of Chemical Engineering, Volume 21, Issue 2, March/April 2026.
ABSTRACT This paper aims to experimentally investigate the mechanisms of microbubble characteristics evolution within an axial pump. The findings will aid in assessing the pump performance by identifying the range of bubble sizes and comparing them with the threshold size (< 300 μm). This study also provides evidence supporting the use of such pumps as
