Global regularity for systems with p-structure depending on the symmetric gradient [PDF]

open access: yesAdvances in Nonlinear Analysis, 2018
In this paper we study on smooth bounded domains the global regularity (up to the boundary) for weak solutions to systems having p-structure depending only on the symmetric part of the gradient.

On the uniqueness for weak solutions of steady double-phase fluids

open access: yesAdvances in Nonlinear Analysis, 2021
We consider a double-phase non-Newtonian fluid, described by a stress tensor which is the sum of a p-Stokes and a q-Stokes stress tensor, with 1

Study on the helicoidal flow through cylindrical annuli with prescribed shear stresses

open access: yesResults in Physics, 2021
In this article, we presented an analysis of the helical flow, for evaluating the incompressible Maxwell fluid indwelling between the two circular regions created by infinitely long concentric circular cylinders.

Large data existence theory for three-dimensional unsteady flows of rate-type viscoelastic fluids with stress diffusion

open access: yesAdvances in Nonlinear Analysis, 2020
We prove that there exists a weak solution to a system governing an unsteady flow of a viscoelastic fluid in three dimensions, for arbitrarily large time interval and data.

The solution of Cahn-Allen equation based on Bernoulli sub-equation method

open access: yesResults in Physics, 2019
In this article, we present an analytical method for finding the solutions of the Cahn-Allen equation (CAE) based on the Bernoulli sub-equation method (BSEM). We find an infinite number of solutions which are divided into eight families.

Peristaltic transport of an Oldroyd‐B fluid in a planar channel

open access: yesMathematical Problems in Engineering, Volume 2004, Issue 4, Page 347-376, 2004., 2004
The effects of an Oldroyd‐B fluid on the peristaltic mechanism are examined under the long wavelength assumption. Analytical expressions for the stream function, the axial velocity, and the pressure rise per wavelength are obtained up to the second order in the dimensionless wave number. The effects of the various parameters of interest on the flow are

On the Optimal Control of a Class of Non-Newtonian Fluids [PDF]

open access: yes, 2013
We consider optimal control problems of systems governed by stationary, incompressible generalized Navier-Stokes equations with shear dependent viscosity in a two-dimensional or three-dimensional domain.
