In fluid dynamics, a potential flow is described by means of a velocity potential φ, being a function of space and time. The flow velocity v is a vector field equal to the gradient, ∇, of the velocity potential φ: This implies that a potential flow is an irrotational flow.
In this manner, what is viscous and inviscid flow?
viscous flow - Flows in which the frictional effects are significant are called viscous flows. inviscid flow. Details. When two fluid layers move relative to each other, a friction force develops between them and the slower layer tries to slow down the faster layer.
What is meant by creeping flow?
Stokes flow (named after George Gabriel Stokes), also named creeping flow or creeping motion, is a type of fluid flow where advective inertial forces are small compared with viscous forces. The Reynolds number is low, i.e. In technology, it occurs in paint, MEMS devices, and in the flow of viscous polymers generally.
What do you mean by viscous flow?
The Viscous Flow. Dictionary definitions – Viscous flow A type of fluid flow in which there is a continuous steady motion of the particles, the motion at a fixed point always remaining constant. Laminar or Laminary consisting of or like thin plates or layers; of or relating to a fluid, streamlined flow.
