Cessation of viscoplastic Poiseuille flow in a square duct with wall slip
(2015)We solve numerically the cessation of the pressure-driven Poiseuille flow of a Bingham plastic under the assumption that slip occurs along the wall following a generalized Navier-slip law involving a non-zero slip yield ...

Comparison of spectral and finite element methods applied to the study of the core-annular flow in an undulating tube
(2002)A Galerkin/finite element and a pseudo-spectral method, in conjunction with the primitive (velocity-pressure) and streamfunction-vorticity formulations, are tested for solving the two-phase flow in a tube, which has a ...

The contribution of active and inactive structures to the statistics of a turbulent pipe flow
(2017)The current study is a short follow-up to our most recent work (Stylianou et al., 2016), where among other things we have presented an effective criterion suitable for distinguishing large-scale coherent structures with ...

Laminar axisymmetric flow of a weakly compressible viscoelastic fluid
(2012)The combined effects of weak compressibility and viscoelasticity in steady, isothermal, laminar axisymmetric Poiseuille flow are investigated. Viscoelasticity is taken into account by employing the Oldroyd-B constitutive ...

Structure-based turbulence model: Application to a rotating pipe flow
(2002)A new approach for modeling the one-point turbulence statistics, which takes into account the information on turbulence structure, has been suggested in Kassinos and Reynolds (Report TF-61, Thermosciences Division, Department ...
