Two-Level Finite Element Approximation for Oseen Viscoelastic Fluid Flow

Mathematics, 2018
In this paper, a two-level finite element method for Oseen viscoelastic fluid flow obeying an Oldroyd-B type constitutive law is presented. With the newly proposed algorithm, solving a large system of the constitutive equations will not be much more ...

Viscoelastic simulation and optimisation of the polymer flow through the hot-end during filament-based material extrusion additive manufacturing

Virtual and Physical Prototyping, 2022
This paper presents a novel Computational Fluid Dynamics (CFD) model that simulates the non-isothermal flow of a viscoelastic fluid through the hot-end in filament-based Material Extrusion Additive Manufacturing (MEX). The hot-end is an essential part of

A numerical stabilization framework for viscoelastic fluid flow using the finite volume method on general unstructured meshes

, 2017
A robust finite volume method for viscoelastic flow analysis on general unstructured meshes is developed. It is built upon a general-purpose stabilization framework for high Weissenberg number flows.

Viscoelastic properties of MR shear thickening fluids

Journal of Fluid Science and Technology, 2014
Magento-rheological Fluid (MRF) and Shear Thickening Fluid (STF) have separately attracted considerable interest due to their fast and reversible response to an external magnetic field or an abrupt shearing loading. In this paper we fabricated a combined

Existence of a weak solution to a nonlinear fluid-structure interaction problem modeling the flow of an incompressible, viscous fluid in a cylinder with deformable walls

, 2012
We study a nonlinear, unsteady, moving boundary, fluid-structure interaction (FSI) problem arising in modeling blood flow through elastic and viscoelastic arteries.

Effects of micro-grooves and fluid viscoelasticity on friction drag reduction in a turbulent boundary layer

Engineering Applications of Computational Fluid Mechanics
To meet the underwater drag reduction needs in engineering applications, one can draw on the drag reduction strategies of marine animals such as sharks, utilizing their surface groove structures and the secretion of viscoelastic drag-reducing mucus to ...

Flow between caoxial rotating disks: with and without externally applied magnetic field

International Journal of Mathematics and Mathematical Sciences, 1981
The problem of flow of a Rivlin-Ericksen type of viscoelastic fluid is discussed when such a fluid is confined between two infinite rotating coaxial disks.

Is subdiffusional transport slower than normal?

, 2012
We consider anomalous non-Markovian transport of Brownian particles in viscoelastic fluid-like media with very large but finite macroscopic viscosity under the influence of a constant force field F.

Flow of viscoelastic fluid in curved tube (Visualization of flow in curved tube and analytical optimization by finite element method)

Nihon Kikai Gakkai ronbunshu, 2015
In the present study we report the flow characteristics of a steady flow of viscoelastic fluid in a curved pipe of 90 degree bend. The liquid mode consideration is a model-fluid, which is newly made to investigate the viscoelastic fluid.
