05.02.2017 Manoj Rajankunte Mahadeshwara

What is Elastohydrodynamic Lubrication (EHL)? Elastohydrodynamic Lubrication – or EHL – is a lubrication regime (a type of hydrodynamic lubrication (HL)) in which significant elastic deformation of the surfaces takes place and it considerably alters […]

Nanoscale Surface Texture To Reduce Bouncing Droplet Contact Time

24.08.2020

Nature continues to shed light on the amazing and wide range of mechanisms employed in the world of plants and animals. Nanoscale (1 x 10 -7 or 3.937 x 10-8 inches) textured surfaces help insects [...]
Stick-slip Phenomenon
