Direct numerical simulation of sharkskin denticles in turbulent channel flow

Published online on 15. March 2016 Direct numerical simulation of sharkskin denticles in turbulent channel flow A. Boomsma, F. Sotiropoulos Abstract: The hydrodynamic function of sharkskin has been under investigation for the past 30 years. Current literature conflicts on whether sharkskin is able to reduce skin friction similar to riblets. To contribute insights toward reconciling

March 2016 Largest global shark biomass found in the northern Galápagos Islands of Darwin and Wolf Pelayo Salinas de León, David Acuña-Marrero, Etienne Rastoin, Alan M Friedlander, Mary K Donovan, Enric Sala ABSTRACT: Overfishing has dramatically depleted sharks and other large predatory fishes worldwide except for a few remote and/or well-protected areas.

A complete protocol for the preparation of chondrichthyan skeletal specimens

A complete protocol for the preparation of chondrichthyan skeletal specimens

Published online on 09. March 2016 A complete protocol for the preparation of chondrichthyan skeletal specimens S. Enault, C. Auclair, S. Adnet, M. Debiais-Thibaud ABSTRACT: The skeleton of cartilaginous fishes is notoriously difficult to prepare, and the literature dealing with the subject is extremely rare compared to other vertebrate groups. As a result, chondrichthyan skeletal

Preparation, anti-biofouling and drag-reduction properties of a biomimetic shark skin surface

Preparation, anti-biofouling and drag-reduction properties of a biomimetic shark skin surface

Published online on 02. March 2016 Preparation, anti-biofouling and drag-reduction properties of a biomimetic shark skin surface Xia Pu, Guangji Li, Hanlu Huang ABSTRACT: Shark skin surfaces show non-smoothness characteristics due to the presence of a riblet structure. In this study, biomimetic shark skin was prepared by using the polydimethylsiloxane (PDMS)-embedded elastomeric stamping (PEES) method.
