A review of turbulent skin-friction drag reduction by near-wall transverse forcing

Pierre Ricco et al.

Summary: The article reviews research on drag reduction techniques, focusing on manipulating the fluid layer near the surface to achieve drag reduction effects, and covers relevant experiments, simulations, and analyses. These methods can achieve drag reduction margins of around 50% in ideal conditions, providing a valuable foundation for future research on reducing friction drag.

Skin-friction reduction using periodic blowing through streamwise slits

X. Q. Cheng et al.

Summary: The study demonstrates that active skin-friction reduction in a turbulent boundary layer can be achieved through time-periodic blowing, leading to more than 70% reduction in friction and positive net power saving. Physical mechanisms involved in friction reduction include streamwise vortices generated by jets from the slits and zero-streamwise-momentum fluid.

Model-based design of riblets for turbulent drag reduction

Wei Ran et al.

Summary: This paper develops a model-based framework to quantify the effect of streamwise-aligned spanwise-periodic riblets on kinetic energy and skin-friction drag in turbulent channel flow. The study shows that triangular riblets can reliably predict drag-reducing trends, but may lead to performance deterioration for large riblets.
