Numerical investigation of riblet-induced drag reduction in turbulent pipe flow

Energy Conversion and Management: X
Biomimetic, shark-skin-inspired riblets are widely studied for drag reduction. However, their performance in cylindrical pipes has received limited attention due to assumptions of similarity with channel flows and the simpler geometry of channel ...

Numerical Simulation of Blade-Shaped Riblets Using LES-Based Methods

Chemical Engineering Transactions, 2023
Passive flow control techniques are widely implemented in many areas of fluid mechanics and aerodynamics, aiming at permanently altering the flow field to suppress undesired phenomena or enhance performance.

Numerical Study of Shark-Skin Memetic Riblets on the Trailing Vortex and Boundary Layer Flow of the Wind Turbine Airfoil

Fluids
Shark skin grooves, known to reduce hydrodynamic drag, have inspired riblet structures for flow control. This study investigates their application to airfoils, where flow separation at high angles of attack (AOA) compromises aerodynamic stability and ...

Energy amplification in channel flow over riblets

2011 IEEE International Symposium on Computer-Aided Control System Design (CACSD), 2011
A number of methods of reducing the drag over airfoils have been investigated. This paper considers the use of riblets, which are structures that run parallel to one another that are positioned longitudinally to the flow. It has been shown experimentally that when the shape, spacing and height of the riblets are optimized, the drag coefficient can be ...
