In the present study, the effect of various twodimensional surface defects (forward-facing steps and ramps, backward-facing steps and ramps, gaps and steps-and-gaps) on boundary-layer transition was experimentally investigated in the transonic regime

Experiments were conducted to study the transition and flow development in a laminar separation bubble (LSB) formed on an aerofoil. The effects of a wide range of free-stream turbulence intensity ( $0.15\,\%< Tu ) and streamwise integral length scale

Wall suction is known to be an effective Laminar Flow Control (LFC) technique to delay laminar-turbulent transition, but its commercial implementation is still limited due to design and integration issues. In particular, current design tools that mod

The large surface area, and ability to retain moisture of textile structures enable microorganisms’ growth, which causes a range of undesirable effects, not only on the textile itself, but also on the user. Moreover, textiles used in health care en

International audience; While it iswell known that increasing surface roughness tends to shift the transition location of a boundary-layer upstream, no model is currently able to accurately predict this shift as a function of the roughness parameters
