After a long period of biological evolution, natural creatures will inevitably evolve body
surfaces suitable for the living environment. The functions of natural biological surfaces are …

Drag reduction has constantly received great attention due to its extensive range of
applications in fluid transportation and vehicle industries. The vital role of two different …

Flexible bionic drag reduction surfaces have attracted increasing attention in recent years
owing to its potential to address the daunting energy crisis. Inspired by the skin of pufferfish …

The key limitations of digital inline holography (DIH) for particle tracking applications are
poor longitudinal resolution, particle concentration limits, and case-specific processing. We …

There is evidence that the application of porous media to the surfaces of bluff bodies
immersed in turbulent fluid flows has a profound effect on the associated aerodynamic …

Taylor–Couette flow with micro-grooves on the rotating inner cylinder is investigated to
reveal the effect of surface structures on drag reduction. The Reynolds number (Re) ranges …

Sharks can swim with excellent hydrodynamic performance under a variety of flow
conditions. The dermal scales of sharks, which can change from an aligned state to a tilted …

A microfiber coating with a hair-like structure is studied as a passive drag reduction device
applied on a cylinder. The coating is applied in the flow-separated region of the cylinder to …

Laser powder bed fusion (L-PBF) technology has remarkable advantages in achieving
lightweight and miniaturized products, and a short manufacturing cycle. However, for the …

Drag reduction for a bluff body is imperative in a time of increasing awareness of the
environmental impact and sustainability of air travel. Microfiber coating has demonstrated its …
