Quantifying the Form‐Flow‐Saltation Dynamics of Aeolian Sand Ripples
Journal of Geophysical Research: Earth Surface, Volume 130, Issue 10, October 2025.Abstract Ripples are the most fundamental and ubiquitous aeolian bedforms formed on sandy surfaces, but their small size and fast response times make them inherently difficult to measure. However, these attributes also make ripples excellent flow indicators, and they have been used extensively in planetary locations for this purpose.

Averaged Reynolds Equation for Flows between Rough Surfaces in Sliding Motion [PDF]
, 2002 The flow between rough surfaces in sliding motion with contacts between these surfaces, is analyzed through the volume averaging method. Assuming a Reynolds (lubrication) approximation at the roughness scale, an average flow model is obtained combining ...

International Journal for Numerical Methods in Fluids, Volume 97, Issue 9, Page 1189-1208, September 2025.This article presents the principles of Finite Element‐Volume discretization and conducts an analysis of its properties and convergence orders. The discretization ensures local mass conservation, second‐order convergence for velocity, and first‐order convergence for pressure.

Microcylinder and Slot Combination for Flow Separation Control Over a Wind Turbine Airfoil
Wind Energy, Volume 28, Issue 7, July 2025.ABSTRACT This study explores a novel passive flow control strategy combining a microcylinder and slot configuration to mitigate flow separation over an S809 wind turbine airfoil under stall conditions at a Reynolds number of 106. Numerical simulations are conducted using the Reynolds‐averaged Navier–Stokes (RANS) approach. The primary objectives are to

International Journal for Numerical Methods in Engineering, Volume 126, Issue 11, 15 June 2025.ABSTRACT In this article, we propose and investigate an explicit partitioned method for solving shock dynamics in fluid–structure interaction (FSI) problems. The method is fully conservative, ensuring the local conservation of mass, momentum, and energy, which is crucial for accurately capturing strong shock interactions.
