I know that by designing an airplane or a car close to a teardrop, we can reduce the drag. My question has to do with the surface friction treatment. Some torpedoes glide in water more efficiently when wrapped in bubble cloaks.

Some feathers have textures to reduce friction. Some modern bathing suits textures help reduce friction.

Are there studies on surface treatments, such as texture, special paint, grooves, or perforations, to reduce drag?


Implied in my question is: If there are any results that do reduce skin friction, where have they been applied?

    $\begingroup$ @sophit I think the question -- asked as "are there studies on this?" truly can be answered with what you have here and the slightest bit of elaboration. Like a sentence or two on a couple of the studies and a link to each, followed by the link you posted supporting the statement "... and thousands more like these." The question is asking, has this been studied, and you provide conclusive proof that yes, in fact it sure has. $\endgroup$

Yes, there are literally thousands of studies on the subject. A keyword search on this link brings up many examples. (credit to Sophit)

There's also a similar question on this site that may be useful. (credit to Peter Kampf)

And there are surface material studies for other purposes that you might also find interesting. (credit to Steve Pemberton)
