Regularity and reduction to a Hamilton-Jacobi equation for a MHD Eyring-Powell fluid

Alexandria Engineering Journal, 2022
The flow under an Eyring-Powell description has attracted interest to model different scenarios related with non-Newtonian fluids. The goal of the present study is to provide analysis of solutions to a one-dimensional Eyring-Powell fluid in ...

Stochastic 2-D Navier-Stokes Equation with Artificial Compressibility [PDF]

, 2007
In this paper we study the stochastic Navier-Stokes equation with artificial compressibility. The main results of this work are the existence and uniqueness theorem for strong solutions and the limit to incompressible flow.

On the existence of global weak solutions of a 2D sediment transport model

Nonautonomous Dynamical Systems, 2022
In the abstract, homogenize the references as follows: In this paper,we study the existence of global weak solutions of a two dimensionnal model. The model is inspired by the one studied in [Math. Models Methods Appl. Sci. 19 (2009), 477-499].

Rayleigh-Benard convection of water conveying copper nanoparticles of larger radius and inter-particle spacing at increasing ratio of momentum to thermal diffusivities

Alexandria Engineering Journal, 2023
As in the case of enhancing the performance of high-temperature superconductors, the dynamics of colloidal mixes of water and copper-based nanoparticles exposed to an inclined magnetic field owing to free convection is a recognized issue.

Enstrophy Dynamics of Stochastically Forced Large-Scale Geophysical Flows [PDF]

, 2001
Enstrophy is an averaged measure of fluid vorticity. This quantity is particularly important in {\em rotating} geophysical flows. We investigate the dynamical evolution of enstrophy for large-scale quasi-geostrophic flows under random wind forcing.

A Single Cell‐Based Model of the Ductal Tumour Microarchitecture

Computational and Mathematical Methods in Medicine, Volume 8, Issue 1, Page 51-69, 2007., 2007
The preinvasive intraductal tumours, such as the breast or prostate carcinomas, develop in many different architectural forms. There are, however, no experimental models explaining why cancer cells grow in these various configurations. We use a mathematical model to compare different proliferative conditions that can lead to such distinct ...

Stagnation‐point flow of the Walters′ B′ fluid with slip

International Journal of Mathematics and Mathematical Sciences, Volume 2004, Issue 61, Page 3249-3258, 2004., 2004
The steady two‐dimensional stagnation point flow of a non‐Newtonian Walters′ B′ fluid with slip is studied. The fluid impinges on the wall either orthogonally or obliquely. A finite difference technique is employed to obtain solutions.

Existence of optimal boundary control for the Navier-Stokes equations with mixed boundary conditions [PDF]

, 2015
Variational approaches have been used successfully as a strategy to take advantage from real data measurements. In several applications, this approach gives a means to increase the accuracy of numerical simulations.

Numerical studies of viscous incompressible flow between two rotating concentric spheres

Journal of Applied Mathematics, Volume 2004, Issue 2, Page 91-106, 2004., 2004
The problem of determining the induced steady axially symmetric motion of an incompressible viscous fluid confined between two concentric spheres, with the outer sphere rotating with constant angular velocity and the inner sphere fixed, is numerically investigated for large Reynolds number.

A stochastic Lagrangian representation of the 3-dimensional incompressible Navier-Stokes equations [PDF]

, 2006
In this paper we derive a representation of the deterministic 3-dimensional Navier-Stokes equations based on stochastic Lagrangian paths. The particle trajectories obey SDEs driven by a uniform Wiener process; the inviscid Weber formula for the Euler ...
