Magneto-hydrodynamic free convection flows of a viscoelastic fluid in porous medium with variable permeability heat source and chemical reaction

open access: yesResults in Physics, 2017
The unsteady free convection flow, with heat and mass transfer, of an electrically conducting viscoelastic fluid, through a porous medium of variable permeability is investigated.

Weak-strong uniqueness and energy-variational solutions for a class of viscoelastoplastic fluid models

open access: yesAdvances in Nonlinear Analysis, 2022
We study a model for a fluid showing viscoelastic and viscoplastic behavior, which describes the flow in terms of the fluid velocity and a symmetric deviatoric stress tensor.

Incompressible limit for compressible viscoelastic flows with large velocity

open access: yesAdvances in Nonlinear Analysis, 2023
We are concerned with the incompressible limit of global-in-time strong solutions with arbitrary large initial velocity for the three-dimensional compressible viscoelastic equations.

Initial boundary value problems for the three-dimensional compressible elastic Navier-Stokes-Poisson equations

open access: yesAdvances in Nonlinear Analysis, 2021
We study the initial-boundary value problems of the three-dimensional compressible elastic Navier-Stokes-Poisson equations under the Dirichlet or Neumann boundary condition for the electrostatic potential.

Fractional relaxation with time-varying coefficient [PDF]

open access: yes, 2014
From the point of view of the general theory of the hyper-Bessel operators, we consider a particular operator that is suitable to generalize the standard process of relaxation by taking into account both memory effects of power law type and time ...

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.

Effects of slip on oscillating fractionalized Maxwell fluid

open access: yesNonlinear Engineering, 2016
The flow of an incompressible fractionalized Maxwell fluid induced by an oscillating plate has been studied, where the no-slip assumption between the wall and the fluid is no longer valid.

Existence of solutions for a shear thickening fluid-particle system with non-Newtonian potential

open access: yesOpen Mathematics, 2018
This paper is concerned with a compressible shear thickening fluid-particle interaction model for the evolution of particles dispersed in a viscous non-Newtonian fluid. Taking the influence of non-Newtonian gravitational potential into consideration, the
