Fractal and statistical characterization of brushstroke on paintings

Maxence Bigerelle, Robin Guibert, Anna Mironova, Frederic Robache, Raphaël Deltombe, Ludovic Nys, Christopher Brown

Identification of an individual artist’s touch on paintings is studied using surface metrology. Paintings’ topographies were measured using focus variation and stitching, creating 13 × 13 mm maps with 1 μ m sampling intervals, and 169 megapixels, with a 10X objective lens. Topographic…

Drag mitigation by steady blowing and Coanda effect on a square back Ahmed body

Baptiste Plumejeau, Laurent Keirsbulck, Jérémy Basley, Marc Lippert, Sébastien Delprat, Wafik Abassi

The impact of converging steady blowing on the global drag past a square back Ahmed bluff body is investigated experimentally. The dynamics of the recirculation bubble are studied for a width to height aspect ratio, w/h of 1.346, with a ground clearance of g/w = 0.154, and for a nominal Reynolds…
