The crucial role of meshing in computational fluid dynamics simulations for organic geometries in paleobiology: Describing fluid dynamics performance through best practices

Methods in Ecology and Evolution, Volume 16, Issue 10, Page 2170-2194, October 2025.
Abstract Computational fluid dynamics (CFD) has become an essential tool for studying fluid interactions in biological systems. While widely used in engineering, its application in the natural sciences, particularly in paleobiology, remains limited due to the challenges of meshing complex organic geometries.

A New Add‐On Flap for Performance Improvement of Small Horizontal Axis Wind Turbines

Energy Science &Engineering, Volume 13, Issue 8, Page 4230-4240, August 2025.
ABSTRACT In the present study, two types of add‐on flaps tangential to the camber line of small horizontal axis wind turbine blade are introduced and their performances on the production power are investigated. The wind turbine of Berlin University (TU‐BERT) is used as the base turbine and the flaps' length, angle, and their locations on the blade are ...

The effect of twist morphing on aerodynamic performance of finite wing at low Reynolds number [PDF]

EPJ Web of Conferences
This study experimentally investigates the effect of twist morphing on the aerodynamic characteristics of a finite wing at low Reynolds numbers (Re). As the base model, a NACA 0018 airfoil with an aspect ratio of 4 is used.

Shape optimization under uncertainty of morphing airfoils

Acta Mechanica, 2017
This paper is devoted to the formulation of a novel optimization under uncertainty framework for the definition of optimal shapes for morphing airfoils, applied here to advancing/retreating 2D airfoils. In particular, the morphing strategy is conceived with the intent of changing the shape at a given frequency to enhance aerodynamic performance.
