The Landau–Levich problem, also known as the Landau–Levich drag problem, deals with the behavior of a liquid film formed on a solid surface when a solid is pulled out of a liquid bath at a constant speed. It is an important problem in fluid dynamics and is particularly relevant in various fields such as coating processes, lubrication, and the study of liquid interfaces.
