Spatial and temporal evolution of a coastal erg margin: The Middle Jurassic Page Sandstone, southern Utah, USA

open access: yesSedimentology, Volume 73, Issue 6, Page 2081-2119, October 2026.
ABSTRACT Aeolian deflationary events are erosive to static stages where sediment supply is insufficient to support bedform migration and preservation in the rock record. In the vicinity of shallow‐marine environments, inland rises of relative water table and associated generation of deflationary super surfaces may be driven by the onset of ...

A Numerical Study on the Motion of Snow Aggregates Freely Falling in Air

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 17, 16 September 2026.
Abstract This paper reports the results of the first quantitative study on the flow fields of freely falling snow aggregates. The motions are investigated by performing numerical simulations of four snow aggregate models consisting of 2, 3, 4, and 5 conformally shaped dendrites of different sizes.

Machine‐Learning Enhanced Parametric Reynolds‐Averaged Navier‐Stokes Equations at the Full‐ and Reduced‐Order Levels

open access: yesInternational Journal for Numerical Methods in Engineering, Volume 127, Issue 17, 15 September 2026.
ABSTRACT In this contribution, we focus on the Reynolds‐averaged Navier‐Stokes (RANS) models and their exploitation to build reliable reduced‐order models to further accelerate predictions for real‐time applications and many‐query scenarios. Specifically, we investigate how machine learning can be employed to enhance the predictive capabilities of the ...

A Sequential Quadratic Numerical Optimization Technique to Compute Critical Flutter Speeds

open access: yesInternational 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 ...
