Linear momentum equation vs navier stokes

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 progressively … Se mer 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 … Se mer Remark: here, the deviatoric stress tensor is denoted $${\textstyle {\boldsymbol {\sigma }}}$$ (instead of $${\textstyle {\boldsymbol {\tau }}}$$ as it was in the general continuum … Se mer The Navier–Stokes equations are strictly a statement of the balance of momentum. To fully describe fluid flow, more information is needed, … Se mer Nonlinearity The Navier–Stokes equations are nonlinear partial differential equations in the general case and so remain in almost every real situation.
