  1. Stokes flow - Wikipedia

    • 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. . This is a typical situation in flows where the fluid velocities are very slow, the viscosities are very large, or the length-scales of the flow are very small.

    Stokes equations

    The equation of motion for Stokes flow can be obtained by linearizing the steady state Navier–Stokes equations. … 展开

    Incompressible flow of Newtonian fluids

    In the common case of an incompressible Newtonian fluid, the Stokes equations take the (vectorized) form:
    where is the velocity of the fluid, is the gradient of the pressure, is the dynamic viscosity, and an … 展开

    Some geometries

    Hele-Shaw flow is an example of a geometry for which inertia forces are negligible. It is defined by two parallel plates arranged very close together with the space between the plates occupied partly by fluid and partl… 展开

    Theorems

    The drag resistance to a moving sphere, also known as Stokes' solution is here summarised. Given a sphere of radius , travelling at velocity , in a Stokes fluid with dynamic viscosity , the drag force is given by: … 展开

     
  1. In fluid dynamics, Stokes' law is an empirical law for the frictional force – also called drag force – exerted on spherical objects with very small Reynolds numbers in a viscous fluid. It was derived by George Gabriel Stokes in 1851 by solving the Stokes flow limit for small Reynolds numbers of the Navier–Stokes equations.
