Layer-averaged Euler and Navier-Stokes equations [PDF]
, 2016 In this paper we propose a strategy to approximate incompressible hydrostatic free surface Euler and Navier-Stokes models. The main advantage of the proposed models is that the water depth is a dynamical variable of the system and hence the model is ...

2D constrained Navier–Stokes equations
Journal of Differential Equations, 2018 We study 2D Navier-Stokes equations with a constraint on $L^2$ energy of the solution. We prove the existence and uniqueness of a global solution for the constrained Navier-Stokes equation on $\R^2$ and $\T$, by a fixed point argument. We also show that the solution of constrained Navier-Stokes converges to the solution of Euler equation as viscosity $

Analytical Solutions to the Navier-Stokes Equations [PDF]
, 2008 With the previous results for the analytical blowup solutions of the N-dimensional Euler-Poisson equations, we extend the similar structure to construct an analytical family of solutions for the isothermal Navier-Stokes equations and pressureless Navier ...

Interpolation, extrapolation, Morrey spaces and local energy control for the Navier--Stokes equations [PDF]
, 2019 Barker recently proved new weak-strong uniqueness results for the Navier-Stokes equations based on a criterion involving Besov spaces and a proof through interpolation between Besov-H{\"o}lder spaces and L 2.

Possibility of Turbulence from a Post-Navier-Stokes Equation [PDF]
, 2006 We introduce corrections to the Navier-Stokes equation arising from the transitions between molecular states and the injection of external energy. In the simplest application of the proposed post Navier-Stokes equation, we find a multi-valued velocity ...

Vanishing viscosity limit of navier-stokes equations in gevrey class
, 2017 In this paper we consider the inviscid limit for the periodic solutions to Navier-Stokes equation in the framework of Gevrey class. It is shown that the lifespan for the solutions to Navier-Stokes equation is independent of viscosity, and that the ...
