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 building the theories, from 1822 (Navier) to 1842-1850 (Stokes). Web8 de jul. de 2011 · A solution of the Navier–Stokes equations is called a velocity field or flow field, which is a description of the velocity of the fluid at a given point in space and time. Once the velocity field is solved for, other quantities of interest (such as flow rate or drag force) may be found.

WebAlthough these equations were written down in the 19th Century, our understanding of them remains minimal. The challenge is to make substantial progress toward a mathematical … WebThe Stokes equation can be rewritten using the streaming function Ψ (r) taking the curl ( ∇ ×) of Eq. (3-6): (A3-1) that is, ∇ 2Φ = 0 and ∇ 2Ψ = Φ. The fluid velocity is directed in parallel with contour lines of the streaming function, namely (A3-2) In a Cartesian coordinate system, this can be written as vx = ∂ Ψ /∂ y and vy = − ∂ Ψ /∂ x.
