He also … The Navier–Stokes equations are partial differential equations which describe the motion of viscous fluid substances, named after French engineer and physicist Claude-Louis Navier and Anglo-Irish physicist and mathematician George Gabriel Stokes. They were developed over several decades of … See more The solution of the equations is a flow velocity. It is a vector field—to every point in a fluid, at any moment in a time interval, it gives a vector whose direction and magnitude are those of the velocity of the fluid at that point in … See more Remark: here, the deviatoric stress tensor is denoted $${\textstyle {\boldsymbol {\sigma }}}$$ (instead of $${\textstyle {\boldsymbol {\tau }}}$$ as it was in the general continuum … See more The Navier–Stokes equations are strictly a statement of the balance of momentum. To fully describe fluid flow, more information is … See more 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 $${\textstyle u_{z}=0}$$ and no dependence of … See more The Navier–Stokes momentum equation can be derived as a particular form of the Cauchy momentum equation, whose general convective form is where • $${\textstyle {\frac {\mathrm {D} }{\mathrm {D} t}}}$$ is … See more The incompressible momentum Navier–Stokes equation results from the following assumptions on the Cauchy stress tensor: • the … See more Nonlinearity The Navier–Stokes equations are nonlinear partial differential equations in the general case and so remain … See more
