Surface roughness and wetting affect microchannel flows in groundbreaking ways.
The study looked at how rough surfaces and wetness affect how liquids move in tiny channels. By using math and models, the researchers found that the angle of the liquid changes a lot because of the bumpy walls and how wet they are. They tested two types of wet surfaces and found that the way liquids spread is influenced by how rough the surface is and how the molecules interact. They also looked at how slippery the surface is and how far apart the bumps are, and found that these factors affect how the liquid moves.
