Incompressible Navier-StokesIn this work, we present a nonlinear variational multiscale finite element method for solving both stationary and transient incompressible Navier-Stokes equations. The method is founded on a two-level decomposition of the approximation space, where a nonlinear artificial ...
The Navier–Stokes equations for an incompressible fluid [1]∂ui∂t=−∂uiuj∂xj+Xi−1ρ∂p∂xi+v∂2ui∂xj2 form the basis for an LES of the PBL, where ui satisfy the continuity equation: [2]∂ui∂xi=0 In eqns [1] and [2], ui are flow velocities in the...

我们通常把这个方程叫做quasilinear hyperbolic perturbation of Naiver-Stokes equations,翻译过来叫做NS方程的拟线性双曲扰动。 因为Quasilinear的PDE是困难的,为了简化问题,有学者把γ∂t(u⋅∇u)项去掉,简化为semilinear hyperbolic perturbation of Naiver-Stokes equations,翻译过来是NS方程的半线性双曲扰动,也有...

For irrotational, incompressible flow with , the Navier-Stokes equation then simplifies to (38) For low Reynolds number, the inertia term is smaller than the viscous term and can therefore be ignored, leaving the equation of creeping motion ...

The aim of this paper is to justify the rigorous derivation of the incompressible Navier–Stokes equations from the nonlinear Vlasov–Fokker–Planck (VFP) equation with a constant temperature. Under the incompressible Navier–Stokes scaling, we first establish the global existence of regular solutions ...
