A Sequential Quadratic Numerical Optimization Technique to Compute Critical Flutter Speeds
International Journal for Numerical Methods in Engineering, Volume 127, Issue 17, 15 September 2026.ABSTRACT A stable sequential quadratic numerical optimization technique is proposed to compute critical flutter speeds without resorting to complex algebra. The solution of the traditional eigenproblem stated in the frequency domain, and whose complex conjugate eigenvalues provide insights on the stability of the dynamic aeroelastic response, is ...

A new drag and lift correlation for spherocylinders from fully resolved Immersed Boundary Method
AIChE Journal, Volume 72, Issue 9, September 2026.Abstract Many industrial processes deal with non‐spherical particles, e.g., mineral mining and biomass conversion. It is crucial to understand the particles' hydrodynamics to control and optimize these processes. To extend the current state‐of‐the‐art from arrays of spherical particles to spherocylindrical particles, we performed extensive particle ...

Experimental Study on Fine Sediment Infiltration (FSI) Processes in Different Gravel Mixtures
River Research and Applications, Volume 42, Issue 7, Page 1573-1585, September 2026.ABSTRACT Fine sediment infiltration (FSI) can lead to riverbed clogging, thereby degrading important habitats for aquatic biota in the hyporheic interstitial zone of gravel‐bed rivers (e.g., by reducing oxygen availability). This stress on rivers may increase from anthropogenic influences and can be counteracted by artificial gravel augmentation to ...

Water Resources Research, Volume 62, Issue 9, September 2026.Abstract Calibration of physics‐based hydrodynamic models of lake water temperature often faces challenges including limited observational data and parameter equifinality, that is, many parameterizations yield similar goodness‐of‐fit to observations. This study presents a framework to investigate how the number and location of observation depths used ...
