A recently developed local-density current functional formalism for confined Bose-condensed superfluids requires visco-elastic spectra which are defined through a finite-frequency extension of the dissipative coefficients entering the linearized hydrodynamic equations of the two-fluid model. We evaluate these spectra for a superfluid with contact interactions in the collisionless regime at fini...

This note deals with the analysis of a model for partial damage, where the rate-independent, unidirectional ow rule for the damage variable is coupled with the rate-dependent heat equation, and with the momentum balance featuring inertia and viscosity according to Kelvin-Voigt rheology. The results presented here combine the approach from Roubí£ek [Rou09, Rou10] with the methods from Lazzaroni/...

An attempt is made to present a theoretical analysis of a transient magnetohydrodynamic (MHD) flow of a visco-elastic fluid (Walter’s B’) past an infinite vertical porous plate embedded in a porous medium with constant permeability in a rotating system in the presence of Hall current when the plate temperature varies periodically with time. The expressions for the non-dimensional velocity field...

In this study, a steady, incompressible, and laminar-free convective flow of a two-dimensional electrically conducting viscoelastic fluid over a moving stretching surface through a porous medium is considered. The boundary-layer equations are derived by considering Boussinesq and boundary-layer approximations. The nonlinear ordinary differential equations for the momentum and energy equations a...

Nano structures such as nanowires, nanobeams and nanoplates have been investigated widely for their innovative properties. In this paper the buckling of nanowires surrounded in a Winkler - Pasternak elastic medium has been examined based on the nonlocal Euler-Bernoully model with considering the surface effects. In the following a parametric study that explores the influence of numerous physica...

A new Galerkin-type procedure is established which, unlike the classical approach, does not rely on the nal shape being composed of linearly independent modes. The procedure is applied to the evolution of a localized buckle of a thin elastic strip within a visco-elastic medium. Unlike the related elastic problem, no clear-cut linear eigenvalues exist to model wavelength and exponential growth/d...

The study of non-equilibrium thermal convection in an anisotropic porous layer saturated with a visco-elastic fluid is carried out to find how the anisotropy and temperature affect onset convection. small perturbation method applied obtain linearized form equations are then solved by using normal mode technique. viscoelasticity considered taking Oldrovd-B momentum equation two separate expressi...
