Tripping and laminar--turbulent transition: Implementation in RANS--EVM
N. Tabatabaei, G. Fahland, A. Stroh +5
Fundamental fluid--mechanics studies and many engineering developments are based on tripped cases. Therefore, it is essential for CFD simulations to replicate the same forced trans…
Coherent structures and secondary flow in turbulent square duct
Marco Atzori, Ricardo Vinuesa, Adrián Lozano-Durán +1
The aim of the present work is to investigate the role of coherent structures in the generation of the secondary flow in a turbulent square duct. The coherent structures are define…
Assessment of skin-friction-reduction techniques on a turbulent wing section
M. Atzori, R. Vinuesa, A. Stroh +2
The scope of the present project is to quantify the effects of uniform blowing and body-force damping on turbulent boundary layers subjected to a non-uniform adverse-pressure-gradi…
Reynolds-number effects in turbulent boundary layers around wing sections
Ricardo Vinuesa, Prabal Negi, Marco Atzori +3
Four well-resolved LESs of the turbulent boundary layers around a NACA4412 wing section, with Rec ranging from 100,000 to 1,000,000, were performed at 5 degree angle of attack. By…
