Web13 de fev. de 2024 · In short, I can understand the main idea - we can not prove that the Navier Stokes Equation will provide a solution that is accurate for all future conditions. But at the same time, I think that the Navier-Stokes Equation is extensively being used to analyze complex real world fluid systems (note: I do not have an engineering background). 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). Web1 de mai. de 2011 · The authors in Ref.
