http://claymath.org/sites/default/files/navierstokes.pdf WebNavier-Stokes equations. Consider the two-dimensional flow of a homogenous and incompressible fluid. The density and the viscosity of the fluid are both assumed to be uniform. We assume that any body forces on the fluid are derived as a gradient of a scalar function. The governing equations for the motion of the fluid are the conservation of ...
