Solving the Navier-Stokes Equations in Fluid Mechanics

WebAn optimal nonlinear Galerkin method with mixed finite elements is developed for solving the two-dimensional steady incompressible Navier-Stokes equations. This method is based on two finite element spaces X H and X h for the approximation of velocity, defined on a coarse grid with grid size H and a fine grid with grid size h ≪ H , respectively, and a finite element … WebThe book is the result of many years of research by the authors to analyse turbulence using Sobolev spaces and functional analysis. In this way the authors have recovered parts of the conventional theory of turbulence, deriving rigorously from the Navier–Stokes equations what had been arrived at earlier by phenomenological arguments. WebJan 30, 2024 · In the fluid dynamics equation, the forces are divided by volume and then can be rearranged as the following equation (in the x-direction): The above equation is known as the famous Navier-Stokes equation. But, the Navier-Stokes equation sometimes refers to the continuity and energy equation as well. 3. THE CONSERVATION OF ENERGY. granby property tax
