WebJul 16, 2024 · The Navier–Stokes equations are nonlinear PDEs which express the conservation of mass, linear momentum, and energy of a viscous fluid. They incorporate … The Navier–Stokes equations are nonlinear partial differential equations in the general case and so remain in almost every real situation. In some cases, such as one-dimensional flow and Stokes flow (or creeping flow), the equations can be simplified to linear equations. The nonlinearity makes most problems difficult or impossible to solve and is the main contributor to the turbulence that the equations model.
