Impact of Density Gradients and Momentum Ratios on Streamwise Circulation at River Confluences
Water Resources Research, Volume 62, Issue 3, March 2026.Abstract Mixing processes in confluences influence concentrations of water quality parameters such as suspended sediment loads and water chemistry in the post‐confluent reach. Thus, improving our understanding of confluence flow structures and mixing is key to predicting the impact of the downstream propagation of pollutants and nutrients.

Effect of Semi-elliptical Outer Blade-surface on the Savonius Hydrokinetic Turbine Performance: A Numerical Investigation [PDF]
Journal of Applied Fluid MechanicsThe Savonius hydrokinetic turbine (SHT) is widely used for generating electricity from running water. However, most optimization work has been carried out on conventional blades with similar concave and convex profiles.

Water Resources Research, Volume 62, Issue 3, March 2026.Abstract At river confluences, the complex hydrodynamics result in significant alterations to flow structures, and the maximum velocity zone serves as one of the primary drivers of pollutant transport and riverbed erosion. This study investigates maximum longitudinal velocity formation in fully ice‐covered confluences, statistically validating the ...

Density–Inertia Coupling Drives Solute Trapping at Vertical Fracture Intersections
Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.Abstract Density‐driven flow and fluid inertia jointly shape solute transport in fracture networks, with implications for hydrogeology and subsurface engineering. While their individual effects are well recognized, their coupled impact remains underexplored.

A Jacobian‐Free Newton‐Krylov Method for Cell‐Centred Finite Volume Solid Mechanics
International Journal for Numerical Methods in Engineering, Volume 127, Issue 3, 15 February 2026.ABSTRACT This study proposes a Jacobian‐free Newton‐Krylov approach for finite‐volume solid mechanics. Traditional Newton‐based approaches require explicit Jacobian matrix formation and storage, which can be computationally expensive and memory‐intensive.
