Abstract Effective properties describe transport processes in porous media, controlled by their geometric characteristics (i.e., pore‐size distribution, connectivity, and porosity) and phase configuration. Estimating effective properties of partially saturated porous media requires performing computationally expensive pore‐scale simulations.

An Enhanced Langmuir Turbulence Parameterization With Nonlocal Momentum and Scalar Fluxes
Abstract Langmuir turbulence plays a critical role in the oceanic surface boundary layer by efficiently transporting momentum, heat, gases, and nutrients. Since its characteristic scale (meters to tens of meters) is far smaller than typical grid cells of ocean general circulation models, it must be parameterized.

A Semi‐Resolved VOF‐DEM Coupling Method for Bedload Transport of Non‐Spherical Particles
Abstract Bedload transport of coarse sediments involves complex particle‐flow interactions that govern sediment motion and bed surface evolution. In this study, a semi‐resolved CFD‐DEM method is developed to simulate bedload sediment dynamics, in which the background fluid information for each particle is calculated using a Gaussian kernel function ...

This study aims to evaluate the potential of a multistage pump design to enhance hemocompatibility in left ventricular assist devices. We found that the two‐stage concept offers favorable hemolysis measures compared to single‐stage designs, as the reduction in peak shear stresses outweighs the disadvantage associated with prolonged residence time ...

A noncanonical role for Jagged1 in endothelial mechanotransduction
The Notch signaling pathway plays a crucial role in regulating endothelial biology. Notch signaling is sensitive to hemodynamic forces and governs mechanically driven cardiovascular development, physiology, and remodeling. This study reveals a non‐canonical role for the Notch ligand Jagged1 in endothelial mechanotransduction.

Textured Piezoelectric Ceramics Printed With Baffled Nozzles
To better align platelet particles in additively manufactured textured ceramics, baffled nozzles were simulated and tested. The simulation included a novel CFD heuristic that considers the entire print path. Printed parts were characterized via microscopy, X‐ray diffraction, and electromechanically and results were compared to the simulation, finding ...

KdV limit for the Vlasov–Poisson–Landau system
Abstract We are concerned with the fluid limit to KdV equations for the one‐dimensional Vlasov–Poisson–Landau system that describes the dynamics of ions in plasma with the electron density determined by the self‐consistent electric potential through the so‐called Boltzmann relation. Formally, it is well known that as the Knudsen number ε→0$\varepsilon \
