created, and in this article the influence of structure on drag reduction efficiency is reviewed. Biomimetic-inspired oleophobic surfaces can be used to prevent contamination of the underwater parts of ships by biological and organic contaminants, including oil. The article also reviews the wetting
of Biomimetic Structures for Fluid Drag Reduction
In this section, we discuss drag reduction efficiency on biomimetic structured surfaces in channels.
Experimental techniques
For the measurement of pressure drop using water and air flows, an experimental flow channel with a rectangular channel was
for hydrophobic surfaces [21].
Fabrication and characterization of biomimetic structures
A shark (Squalus acanthias, L. Squalidae) was used for creating a shark skin replica [21]. A shark is an aquatic animal, and its skin is permanently exposed to contamination from marine organisms, e.g., bacteria

the author and which repeatedly finds its way into numerous examples and problems is the tribology of biological objects. Since Popov knows biological and biomimetic systems from his own collaborative research with biologists [1][2][3], the book is not only an excellent starting point for engineers
