applications when modeling turbulent flows. Another technique for solving numerically the Navier–Stokes equation is the Large-eddy simulation (LES). This approach is computationally more expensive than the RANS method (in time and computer memory), but produces better results since the larger turbulent...
Thus the governing equation is an integro-differential equation and not convenient for numerical computation. An equivalent weak or variational form of the equation, proved to produce the same velocity solution as the Navier–Stokes equation,[18] is given by, for divergence-free test functions ...
Physically, there would be some other non-ideal terms, e.g. a forcing term and a linear frictional damping term ∝v which will remove energy at large scales, thereby making the inverse energy cascade stationary. The Navier-Stokes equation in Fourier form is ∂ψk∂t+γk2ψk=12∑k=k...

equation with the inhomogeneous Neumann data as well as the pressure estimate in the critical Besov space framework. The proof heavily depends on the explicit expression of the fundamental integral kernel of the Lagrange transformed linearized Stokes equations and the almost orthogonal estimates with the...
As such, transport equations are solved for each of the non-zero components of 〈uiuj〉. The transport equations for the individual stress components are obtained from the Reynolds-stress transport equation, given in canonical form as (4)DDt(ρ〈uiuj〉)=ρ(Pij+Dij+πij−ɛij), where...
The multiparameter continuation described previously was done by augmenting the Navier–Stokes equation by equations that describe the vortex-birth condition. The solution of this augmented system was obtained by Galerkin's finite element method. The formulation and solution method for the multiparameter...
