“supercriticality barrier” for the global regularity problem for the Navier-Stokes equation, which roughly speaking asserts that it is not possible to establish global regularity by any “abstract” approach which only uses upper bound function space estimates on the nonlinear part of the equation,...
The primitive variable formulation of conserved incompressible Navier–Stokes equation is solved in a 2D lid-driven cavity using upwind scheme. First-order and third-order accurate upwind schemes are applied on the convection terms of the Navier–Stokes equation. The equations are discretized using ...
Navier-Stokes equation A partial differential equation which describes the conservation of linear momentum for a linearly viscous (newtonian), incompressible fluid flow. In vector form, this relation is written as Eq. (1), (1) where &rgr; is fluid density, V is fluid velocity, p is ...
Eq. (29), which is, in essence, the Laplace equation, can be solved for many flows of practical significance by expressing the pressure in terms of solid spherical harmonics [1,6]. Then by inserting this solution into the original Stokes equation, the velocity field can be evaluated as ori...
