Stokes flow

Stokes flow is a kind of water flow that is slow and gentle. It's named after the scientist Sir George Stokes, who studied this kind of motion. When water moves slowly, it tends to form a pattern of swirling circles called vortices. This happens because the molecules of water bump into each other and create swirling shapes. Stokes flow is like a river with these whirlpools as its water flows slowly in one direction. Scientists study this kind of flow to learn more about how water behaves.
