WebThis is called the Navier–Stokes existence and smoothness problem. The problem, restricted to the case of an incompressible fluid , is to prove either that smooth, globally defined solutions exist that meet certain conditions, or that they do not always exist and the equations break down. Web10 de nov. de 2008 · From Wikipedia, the free encyclopedia. The Navier–Stokes equations, named after Claude-Louis Navier and George Gabriel Stokes, describe the motion of viscous fluid substances such as liquids and gases. These equations arise from applying Newton's second law to fluid motion, together with the assumption that the fluid …
