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 equations and in the incompressible flow section). The compressible … 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 Nonlinearity The Navier–Stokes equations are nonlinear partial differential equations in the general case and so remain … 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 See more The incompressible momentum Navier–Stokes equation results from the following assumptions on the Cauchy stress tensor: • the stress is Galilean invariant: it does not depend directly on the flow velocity, but only on spatial … See more Taking the curl of the incompressible Navier–Stokes equation results in the elimination of pressure.
