Stokes flow
From Wikipedia, the free encyclopedia
Stokes flow is a type of flow where inertial forces are small as compared to viscous forces. The Reynolds number is low, usually Re<1. This is a typical situation in MEMS devices.
For this type of flow, the Navier-Stokes equations simplify as:
<math>0 = \nabla \mathbb{P} + \nu \nabla^2 \mathbf{u} + \rho\mathbf{f}</math>
Stokes flow is very common in the processing of polymers and other materials.
