2 A Computational Model for Visco - Elastic
نویسنده
چکیده
Particle diiusion in rotating drums is studied via computer simulations using a full 3-D model which does not involve any arbitrary input parameters. The diiusion coeecient for single-component systems agree qualitatively with previous experimental results. On the other hand, the diiusion coeecient for two-component systems is shown to be a highly nonlinear function of the rotation velocity. It is suggested that this results from a competition between the diiusive motion parallel to, and owing motion perpendicular to the axis of rotation.

A Computational Approach to the Flow of Walter’s Liquid B′ through Annulus of Coaxial Porous Circular Cylinders for High Suction Parameter (RESEARCH NOTE)
The present investigation studies the behavior of steady flow of visco-elastic liquid between two porous coaxial circular cylinders, where both the cylinders are rotating with different uniform angular velocities about the common axis. In addition, the inner cylinder has uniform velocity along the axis and the visco-elastic fluid, which is a Walters liquid B′, is allowed to flow in the annulus....

متن کاملNonlocal Vibration Behavior of a Viscoelastic SLGS Embedded on Visco- Pasternak Foundation Under Magnetic Field
This paper is concerned with the surface and small scale effects on transverse vibration of a viscoelastic single-layered graphene sheet (SLGS) subjected to an in-plane magnetic field. The SLGS is surrounded by an elastic medium which is simulated as Visco-Pasternak foundation. In order to investigate the small scale effects, the nonlocal elasticity theory is employed due to its simplicity and ...

In this study, the analysis of transient thermoelastic response of a functionally graded (FG) non-axisymmetric viscoelastic cylinder is presented. The material properties are assumed to be time- dependent and radially and circumferentially non-homogeneous. The finite element (FE) formulations of the thermoelastic problem are obtained using the virtual work method and all the coupling terms are ...
