A research has been carried out by a group of researchers from UCLA to find out impact of surface roughness on speed and friction. The study researchers have found that rough surfaces are able to reduce drags, better compared to smooth surfaces in some cases.

It is a significant finding as it can change the way how seafaring vessels to swimming suits are designed. An experiment was carried out in which fluid flow was checked between two surfaces that were lined with tiny ridges.

It was noticed that the flow of fluid was more efficient. It shall however, be noted that this has not been the first time when researchers have tried to come up with models based on rough ridges to reduce drag.

But they were not able to register success in the same. This time, the researchers have taken help of superhydrophobicity and with the same; they were able to come up with ridges that trapped air bubbles.

Laminar and turbulent flows, both were modeled by the researchers. To their surprise, the efficiency was found more in turbulent conditions. The finding is said to prove quite beneficial when it comes to designing long-distance cargo vessels and shipping containers. The increased efficiency in return will prove beneficial in bringing a decline in fuel usage.
