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 … Ver más 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 … Ver más Remark: here, the deviatoric stress tensor is denoted $${\textstyle {\boldsymbol {\sigma }}}$$ (instead of $${\textstyle {\boldsymbol {\tau }}}$$ as it was in the general continuum … Ver más The Navier–Stokes equations are strictly a statement of the balance of momentum. To fully describe fluid flow, more information is … Ver más Nonlinearity 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 … Ver más The Navier–Stokes momentum equation can be derived as a particular form of the Cauchy momentum equation, whose general convective form is where Ver más The incompressible momentum Navier–Stokes equation results from the following assumptions on the Cauchy stress tensor: Ver más Taking the curl of the incompressible Navier–Stokes equation results in the elimination of pressure. This is especially easy to see if 2D Cartesian flow is assumed (like in the degenerate 3D case with $${\textstyle u_{z}=0}$$ and no dependence of … Ver más Web29 de mar. de 2004 · The main goal of this chapter is to present the Navier-Stokes equation, both for incompressible and compressible fluids.
