This results in the integral form of the equation, which can then be used to analyze the behavior of the fluid. What are the assumptions made in deriving the Navier-Stokes equation? The derivation of the Navier-Stokes equation involves several assumptions, including that the fluid is ...
Taking the curl of the Navier–Stokes equation results in the elimination of pressure. This is especially easy to see if 2D Cartesian flow is assumed (w = 0 and no dependence of anything on z), where the equations reduce to:Differentiating the first with respect to y, the second with ...
Navier–Stokes equation [Wikipedia] In physics, the Navier–Stokes equations, named after Claude-Louis Navier and George Gabriel Stokes, describe the motion of fluid substances. These equations arise from applying Newton's second law to fluid motion, together with the assumption that the stress in...
The derivation of the Navier–Stokes equation from the principle of minimal deformation As a special case of the general principle of minimal entropy production discussed in earlier parts of this series, we relate here the hydrodynamic Navier......

A variational derivation of the Navier-Stokes equations based on the exergy destruction of the flow 来自 ResearchGate 喜欢 0 阅读量: 22 作者: E Sciubba 摘要: A novel procedure for calculating the flow field of viscous fluids is proposed and its implications explored. The calculational approach is...
Then the measure μ is said to be a stationary statistical solution of the Navier–Stokes equations if μ satisfies the following (stationary) Liouville-type equation: (3.1)∫H∫VQ(u)Φ′(u)dxdμ(u)=0for all suitable test functions Φ, and the energy inequality: (3.2)∫H∫Vν|∇u|...
In fluid mechanics, the Navier-Stokes equations are partial differential equations that express the flow of viscous fluids.
Tags Compressible Fluid Navier-stokes In summary: Interesting. The Boussinesq approximation says that if you know the density of the fluid and the compressibility of the fluid, you can approximate the pressure and velocity by solving the equation for ##\vec{p}## and ##\vec{v}##. Jun 29,...
