Taking the curl of the incompressible Navier–Stokes equation results in the elimination of pressure. This is especially easy to see if 2D Cartesian flow is assumed (like in the degenerate 3D case with and no dependence of anything on ), where the equations reduce to: Differentiating the first with respect to , the second with respect to and subtracting the resulting equations will eliminate pressure and any conservative force. For incompressible flow, defining t… WebVolume viscosity (also called bulk viscosity, or dilatational viscosity) is a material property relevant for characterizing fluid flow.
