| Summary: | The paper provides a review of publications devoted to the study of the hydrodynamic effect of «shark
skin» and its possible applications in technical systems, in particular in vane pumps. The hydrodynamic
effect of «sharkskin» occurs due to roughness (riblets) oriented along the flow and allows to reduce
the amount of hydraulic resistance in the near-wall region. An analysis of studies on the morphology
and replication of shark skin, as well as some options for applying this effect in technical systems, is
carried out. Examples of a number of the most interesting, according to the authors, works that are in
the public domain are given. Some features of the presented studies are noted. A conclusion is made
about the current state of biomimetic technologies in hydraulic engineering and about the development
trends in this area. |
