The effect of converging–diverging riblet-type surface roughness (riblets arranged in a
'herringbone'pattern) are investigated experimentally in a zero pressure gradient turbulent …

Aquatic animals have developed effective strategies to reduce their body drag over a long
period of time. In this work, the influence of the scales of fish on the laminar-to-turbulent …

Classical vortex generators, known for their efficiency in delaying or even inhibiting
boundary layer separation, are here shown to be coveted devices for transition to turbulence …

The surface topology of the scale pattern from the European sea bass (Dicentrarchus labrax)
was measured using a digital microscope and geometrically reconstructed using computer …

In this study we investigate the influence of an array of miniature vortex generators (MVGs)
in a zero-pressure-gradient turbulent boundary layer (ZPG TBL) by means of a large-eddy …

This experimental investigation studies the impact of streaks on two-dimensional laminar
separation bubbles forming over an aerofoil. Streaks are introduced into the boundary layer …

Flow through mechanical aortic valves (MAVs) has been constantly associated to higher
haemolysis and platelet activation levels with respect to native valves, due to non …

The effect of shark skin on the boundary-layer separation process under dynamic conditions
(maneuvers) has been studied experimentally. We use a foil covered with biomimetic shark …

Spanwise arrays of miniature vortex generators (MVGs) are used to generate energetic
transient disturbance growth, which is able to modulate the boundary layer flow with steady …

Stabilization of two-dimensional disturbances in hypersonic boundary layer flows by finite-
amplitude streaks is investigated using nonlinear parabolized stability equations. The …
