Eigenvalues of the time—dependent fluid flow problem I

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 13, Issue 1, Page 139-144, 1990., 1988
The direct and inverse boundary value problems for the linear unsteady viscous fluid flow through a closed conduit of a circular annular cross‐section Ω with arbitrary time‐dependent pressure gradient under the third boundary conditions have been investigated.

POD Applied to Numerical Study of Unsteady Flow Inside Lid-driven Cavity

open access: yesJournal of Mathematical Study, 2018
Flow inside a lid-driven cavity (LDC) is studied here to elucidate bifurcation sequences of the flow at super-critical Reynolds numbers (Recr1) with the help of analyzing the time series at most energetic points in the flow domain.

Local stability of energy estimates for the Navier--Stokes equations

open access: yes, 2017
We study the regularity of the weak limit of a sequence of dissipative solutions to the Navier--Stokes equations when no assumptions is made on the behavior of the ...

A counterexample to the smoothness of the solution to an equation arising in fluid mechanics [PDF]

open access: yes, 2002
We analyze the equation coming from the Eulerian-Lagrangian description of fluids. We discuss a couple of ways to extend this notion to viscous fluids. The main focus of this paper is to discuss the first way, due to Constantin.

Well-Posedness for the 2D Non-Autonomous Incompressible Fluid Flow in Lipschitz-like Domain

open access: yesJournal of Partial Differential Equations, 2019
This paper is concerned with the global well-posedness and regularity of weak solutions for the 2D non-autonomous incompressible Navier-Stokes equation with a inhomogeneous boundary condition in Lipschitz-like domain.

A stochastic perturbation of inviscid flows

open access: yes, 2010
We prove existence and regularity of the stochastic flows used in the stochastic Lagrangian formulation of the incompressible Navier-Stokes equations (with periodic boundary conditions), and consequently obtain a $\holderspace{k}{\alpha}$ local existence

Approximation of 2D Euler Equations by the Second-Grade Fluid Equations with Dirichlet Boundary Conditions

open access: yes, 2014
The second-grade fluid equations are a model for viscoelastic fluids, with two parameters: $\alpha > 0$, corresponding to the elastic response, and $\nu > 0$, corresponding to viscosity.

Regularity of transition semigroups associated to a 3D stochastic Navier-Stokes equation

open access: yes, 2006
A 3D stochastic Navier-Stokes equation with a suitable non degenerate additive noise is considered. The regularity in the initial conditions of every Markov transition kernel associated to the equation is studied by a simple direct approach. A by-product
