Effect of Fluid Viscoelasticity on Turbulence and Large-Scale Vortices behind Wall-Mounted Plates

Advances in Mechanical Engineering, 2014
Direct numerical simulations of turbulent viscoelastic fluid flows in a channel with wall-mounted plates were performed to investigate the influence of viscoelasticity on turbulent structures and the mean flow around the plate.

Asymptotic Behavior of a Viscoelastic Fluid in a Closed Loop Thermosyphon: Physical Derivation, Asymptotic Analysis, and Numerical Experiments

Abstract and Applied Analysis, 2013
Fluids subject to thermal gradients produce complex behaviors that arise from the competition with gravitational effects. Although such sort of systems have been widely studied in the literature for simple (Newtonian) fluids, the behavior of viscoelastic

Investigation of second grade viscoelastic non-Newtonian nanofluid flow on the curve stretching surface in presence of MHD

Results in Engineering, 2023
MHD extended flow of second-grade viscoelastic nanofluid is studied in two-dimensional mode on a curve stretching surface. Items like Joule heating and curvature parameter have been applied to inspect the heat transfer and mass transfer rates. To produce

Numerical solutions of convective transport on Brinkman-viscoelastic fluid over a bluff body saturated in porous region

Case Studies in Thermal Engineering, 2021
Convective is a fundamental mechanism in heat transfer analysis. Convective heat transport refers to the transfer of heat from one stage to another. In order to produce the preferred output, it is critical to understand the properties of fluid flow.

Investigation of particle lateral migration in sample-sheath flow of viscoelastic fluid and Newtonian fluid

, 2016
In this work, particle lateral migration in sample-sheath flow of viscoelastic fluid and Newtonian fluid was experimentally investigated. The 4.8-μm micro-particles were dispersed in a polyethylene oxide (PEO) viscoelastic solution, and then the solution

A Backwards-Tracking Lagrangian-Eulerian Method for Viscoelastic Two-Fluid Flows [PDF]

, 2021
A new Lagrangian–Eulerian method for the simulation of viscoelastic free surface flow is proposed. The approach is developed from a method in which the constitutive equation for viscoelastic stress is solved at Lagrangian nodes, which are convected by ...

Viscoelastic behaviour of basaltic lavas. [PDF]

, 2004
The rheological properties of basaltic lavas from Etna, Hawai′i and Vesuvius have been investigated at temperatures between 500 and 1150°C using a small-strain oscillatory shear. The viscoelastic response of the lavas to small, forced, sinusoidal torques

Thermosolutal Instability in Compressible Viscoelastic Dusty Fluid through Porous Medium

, 2013
Thermosolutal instability in a compressible Walters B’ viscoelastic fluid with suspended particles through a porous medium is considered. Following the linearized stability theory and normal mode analysis, the dispersion relation is obtained.

Dynamic analysis and uncertainty modeling of viscoelastic beam response to fluid stimulation: Insights into nonlinear effects and velocity uncertainties

Applied Ocean Research
This study investigates nonlinear vibrations in viscoelastic beams induced by external fluid flow. We introduce novel equations considering the Kelvin-Voigt viscoelastic model, geometric nonlinearity, and uncertainties in flow velocity for a more ...
