To counter lubricant shortage at a frictional contact (starvation) lubrication liquids e.g.
oils are actively transported from a distant location towards the undersupplied tribocontact.
This is done via small channels or generally via structures cut into a flat surface. In this
way one can use capillary force as a cheap and reliable driver of the lubricant flow. Numerical
modeling and experiments show that this method can be considered a promising new option to
enhance tribocontact operation.
