Incompressible Navier-Stokes Equations: Example of no solution at $R^3$ and $t=0$
Abstract
We provide an example of a smooth, divergence-free velocity vector field for incompressible fluid occupying all of space, and smooth vector field for which the Navier-Stokes equation for incompressible fluid does not have a solution for any position in space at . The velocity vector field ; where is smooth, divergence-free, continuously differentiable , has bounded energy , zero velocity at coordinate origin, and velocity converges to zero for . The vector field is smooth, continuously differentiable , converging to zero for . Applying and in the Navier-Stokes equation for incompressible fluid results with three mutually different solutions for pressure , one of which includes zero division with zero term at , which is indeterminate for all positions .
