WebNavier-Stokes equation, in fluid mechanics, a partial differential equation that describes the flow of incompressible fluids. The equation is a generalization of the equation devised by … WebJun 29, 2024 · The middle equation in Equation is the famous Navier-Stokes equation, named after the French physicist Navier and the Irish physicist Stokes. Navier was first to derive the equations, but the understanding of the physical mechanism behind the viscous term was first explained by Stokes, hence the name of the equations.
WebThe Navier-Stokes equation--shown above--or some form of it is typically at the heart of any analysis of fluid flow, which includes gases and plasma in motion. This equation is employed to analyze both laminar and turbulent flow regimes and can be utilized for 1-D, 2-D, or 3-D evaluations. Fluid flows may be classified in a number of ways.

WebApr 16, 2024 · In most cases it is useful to define the terms you want to talk about, e.g., what exactly do you mean when your are talking about Euler and Navier-Stokes equations. The classical Navier-Stokes equations consists of at least two different parabolic effects, heat conduction according to Fouriers law and viscous effects according to Stokes law. The difference between them and the closely related Euler equations is that Navier–Stokes equations take viscosity into account while the Euler equations model only inviscid flow.
