Flow over riblet curved surfaces
Journal of Physics: Conference Series, 2011 The present work studies the mechanics of turbulent drag reduction over curved surfaces by riblets. The effects of surface modification on flow separation over steep and smooth curved surfaces are investigated. Four types of two-dimensional surfaces are studied based on the morphometric parameters that describe the body of a blue whale.

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 ...

Form and function of anguilliform swimming
Biological Reviews, Volume 99, Issue 6, Page 2190-2210, December 2024.ABSTRACT Anguilliform swimmers are long and narrow animals that propel themselves by undulating their bodies. Observations in nature and recent investigations suggest that anguilliform swimming is highly efficient. However, understanding the underlying reasons for the efficiency of this type of locomotion requires interdisciplinary studies spanning ...
