AIAA Journal, 2018
Koch-like riblets that iteratively protrude toward the outside (the fluid region) or cave in at the wall are examined. The near-wall microscopic fluid problem is addressed by solving for the Stokes flow with a boundary element method, yielding slip lengths for all the surface shapes considered.

The effectiveness of riblets in reducing friction drag has been well assessed by many experiments in flat plate flow in the end of the last century. Both theory and experiments showed that the effect of riblets only depends on the local Reynolds number, however some experiments in pressure gradient flow showed increased effectiveness of riblets.

Coherent structures and riblets
Applied Scientific Research, 1995We study the effect of the riblets on the coherent structures near the wall. The emphasis is put on the genesis of the quasi-streamwise vortices in the presence of the riblets. The quasi-streamwise vortices regenerate by the tilting of wall normal vorticity induced by prevailing structures. This requires a mechanism which leads to a temporal streamwise

Analyses of Non Local Effects of Riblets
Aerotecnica Missili & Spazio, 2016The paper deals with the effects of pressure gradient and shock wave on riblet performance. A model for the numerical simulations of riblets at high Reynolds numbers is presented and results of airfoil flows in subsonic and transonic conditions are discussed and compared with available experiments.

Numerical investigation of V-shaped riblets and an improved model of riblet effects
Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science, 2017Symmetric V-shaped riblets are simulated by using the computational fluid dynamic method to understand the riblet effects on the turbulent boundary layer and the skin friction reduction. Three classical turbulence models, namely Spalart–Allmaras, shear stress transport, and re-normalization group k-epsilon models, are investigated under different grid
