Web18. aug 2024 · But actually this is quite difficult. It was done in the 1840’s by Sir George Gabriel Stokes. He found what has become known as Stokes’ Law: the drag force F on a sphere of radius a moving through a fluid of viscosity η at speed v is given by: (1.7.1) F = 6 π a η v. This drag force is directly proportional to the radius. WebWeak form of steady Navier-Stokes equations with special boundary condition.
