Unsteady evaporation and entropy generation in a Couette flow [PDF]

open access: yesAdvances in Mechanical Engineering, 2017
A numerical analysis is carried out for unsteady evaporation of a Newtonian fluid Couette flow confined within a cylindrical annulus with relative rotation. The inner wall is humid and adiabatic, whereas the outer one is isothermal and impermeable.

Basic Flows of Generalized Second Grade Fluids Based on a Sisko Model

open access: yesInternational Journal of Applied Mechanics and Engineering, 2017
The present investigation is concerned with basic flows of generalized second grade fluids based on a Sisko fluid. After formulation of the general equations of motion three simple flows of viscoplastic fluids of a Sisko type or fluids similar to them ...

Efficient numerical schemes for viscoplastic avalanches. Part 2: the 2D case [PDF]

open access: yes, 2018
This paper deals with the numerical resolution of a shallow water viscoplastic flow model. Viscoplastic materials are characterized by the existence of a yield stress: below a certain critical threshold in the imposed stress, there is no deformation and ...

Turbulence strength in ultimate Taylor-Couette turbulence [PDF]

open access: yes, 2017
We provide experimental measurements for the effective scaling of the Taylor-Reynolds number within the bulk $\text{Re}_{\lambda,\text{bulk}}$, based on local flow quantities as a function of the driving strength (expressed as the Taylor number Ta), in ...

A new class of Finitely Extensible Nonlinear Elastic FENE-P model obtained with a thermodynamical approach and the use of compressible natural configurations. Part I: Isothermal deformations

open access: yesApplications in Engineering Science, 2023
In a recent contribution to the fundamental understanding of polymer fluid dynamics, Khambhampati and Rajagopal (2021) established a connection between the natural configuration theory of Rajagopal and Srinivasa (2000) and the FENE-P model of Bird et al.

Comparing macroscopic continuum models for rarefied gas dynamics : a new test method [PDF]

open access: yes, 2006
We propose a new test method for investigating which macroscopic continuum models, among the many existing models, give the best description of rarefied gas flows over a range of Knudsen numbers.

Computer simulations of an impurity in a granular gas under planar Couette flow

open access: yes, 2011
We present in this work results from numerical solutions, obtained by means of the direct simulation Monte Carlo (DSMC) method, of the Boltzmann and Boltzmann--Lorentz equations for an impurity immersed in a granular gas under planar Couette flow.
