Large-Eddy Simulations of turbulent compressible channel flow over riblets

, 2002
International audienceThis work presents a numerical study of a weakly-compressible turbulent channel flow with one wall equipped with riblets of low height and of spanwise wavelength equal to 20 wall units.

Stability of the flow over superhydrophobic micro roughnesses: The influence of the interface

International Journal of Thermofluids
Superhydrophobic surfaces are known for their drag reduction properties. However, the interface between the lubricant and the overlying flow may easily become unstable, leading to the depletion of the superhydrophobic layer and to a consequent drag ...

Review of Passive Flow Control Methods for Compressor Linear Cascades

Applied Sciences
This paper reviews the evolution of flow control methods for bladed linear cascades, focusing on passive techniques like riblets, grooves, vortex generators (VGs), and blade slots, which have proven effective in reducing drag, suppressing flow separation,

Performance Assessment of a Transonic Wing–Body Configuration with Riblets Installed

, 2016
The effectiveness of the riblets, one of the most interesting drag-reduction device, is discussed in this paper. Numerical simulations by the Reynolds-averaged Navier–Stokes equations with the riblets properly taken into account are presented.
