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.

Global Regularity for the Two-dimensional Boussinesq Equations Without Diffusivity in Bounded Domains

open access: yes, 2018
We address the well-posedness for the two-dimensional Boussinesq equations with zero diffusivity in bounded domains. We prove global in time regularity for rough initial data: both the initial velocity and temperature have $\epsilon$ fractional ...

On a viscous two-fluid channel flow including evaporation

open access: yesOpen Mathematics, 2018
In this contribution a particular plane steady-state channel flow including evaporation effects is investigated from analytical point of view. The channel is assumed to be horizontal.

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

Global well-posedness of a nonlinear Boussinesq-fluid-structure interaction system with large initial data

open access: yesAdvances in Nonlinear Analysis
In this article, we consider the global well-posedness of the initial-boundary value problem to a nonlinear Boussinesq-fluid-structure interaction system, which describes the motion of an incompressible Boussinesq-fluid surrounded by an elastic structure

Smooth solutions for the dyadic model

open access: yes, 2010
We consider the dyadic model, which is a toy model to test issues of well-posedness and blow-up for the Navier-Stokes and Euler equations. We prove well-posedness of positive solutions of the viscous problem in the relevant scaling range which ...

Asymptotic analysis of Leray solution for the incompressible NSE with damping

open access: yesDemonstratio Mathematica
In 2008, Cai and Jiu showed that the Cauchy problem of the Navier-Stokes equations, with damping α∣u∣β−1u\alpha {| u| }^{\beta -1}u for α>0\alpha \gt 0 and β≥1\beta \ge 1 has global weak solutions in L2(R3){L}^{2}\left({{\mathbb{R}}}^{3}).

Application of QLM-Rational Legendre collocation method towards Eyring-Powell fluid model

open access: yesNonlinear Engineering, 2019
In this paper, a spectral method based on the rational Legendre functions is discussed to approximate the solution of the boundary layer flow of an Eyring-Powell non-Newtonian fluid over a stretching sheet.

Global inviscid limit of 2D, stationary Navier-Stokes and stability of Prandtl expansions

open access: yesForum of Mathematics, Pi
In this work, we establish the convergence of 2D, stationary Navier-Stokes flows with viscosity $\varepsilon> 0$ , $(u^\varepsilon , v^\varepsilon )$ to the classical Prandtl boundary layer, $(\bar {u}_p, \bar {v}_p)$ , posed on the ...

A computational model for three-phase fluid-structure interaction and its application to cellulose microfibril dynamics

open access: yesComputational and Mathematical Biophysics
Three-phase fluid-structure interaction (FSI) problems couple the motion of solid structures and two different fluids, often exhibiting complex dynamics and posing challenges for computational investigation. The main objective of this paper is to present
