Drag Reduction on Microstructure Surfaces
Sakarya Üniversitesi Fen Bilimleri Enstitüsü DergisiIn this study, experimental work in the literature about friction on bird-feather like structures has been reviewed and one of these was modeled by using CFD (Computational Fluid Dynamics) to obtain minimum grid parameters.

Ecology and Evolution, Volume 15, Issue 10, October 2025.The family Anomiidae displays taxonomic ambiguity due to morphological plasticity. We resurrect Heteranomia aculeata and Pododesmus glaucus, while reclassifying Isonomia umbonata as Pododesmus umbonatus. Phylogenetic analyses confirm these revisions and the monophyly of all genera within Anomiidae, with Pododesmus as the earliest‐diverging lineage ...

Scalable Fabrication of Height‐Variable Microstructures with a Revised Wetting Model
Advanced Engineering Materials, Volume 27, Issue 13, July 2025.Height‐variable microstructures are fabricated using a scalable CO2 laser machining approach, enabling precise control of wettability through structural gradients. Classical wetting models fail to capture height‐induced effects, necessitating a revised theoretical framework.

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
