WebThe Navier-Stokes equations, named after Claude-Louis Navier and George Gabriel Stokes, are a set of equations that describe the motion of fluid substances like liquids and gases. These equations establish that changes in momentum (acceleration) of the particles of a fluid are simply the product of changes in pressure and dissipative viscous forces … 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 … 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 • $${\textstyle {\frac {\mathrm {D} }{\mathrm {D} t}}}$$ is … 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 … Ver más
