Large-eddy simulations of the turbulent Hartmann flow close to the transitional regime
(2007)
A series of large-eddy simulations (LES) of turbulent and transitional channel flows of a conductive fluid under the effect of a uniform magnetic field applied in the wall-normal direction, usually referred to as Hartmann ...
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 ...
Direct numerical simulation of particle laden flow in a human airway bifurcation model
(2016)
During the delivery of inhaled medicines, and depending on the size distribution of the particles in the formulation, airway bifurcations are areas of preferential deposition. Previous studies of laminar flow through airway ...
Performance of the finite volume method in solving regularised Bingham flows: Inertia effects in the lid-driven cavity flow
(2014)
We extend our recent work on the creeping flow of a Bingham fluid in a lid-driven cavity, to the study of inertial effects, using a finite volume method and the Papanastasiou regularisation of the Bingham constitutive model ...
Thixotropic flow past a cylinder
(2014)
We study the flow of a thixotropic fluid around a cylinder. The rheology of the fluid is described by means of a structural viscoplastic model based on the Bingham constitutive equation, regularised using the Papanastasiou ...
Core of the magnetic obstacle
(2010)
Rich recirculation patterns have been recently discovered in the electrically conducting flow subject to a local external magnetic termed "the magnetic obstacle" (E.V. Votyakov, Y. Kolesnikov, O. Andreev, E. Zienicke, and ...
On the analogy between streamlined magnetic and solid obstacles
(2009)
Analogies are elaborated in the qualitative description of two systems: the magnetohydrodynamic (MHD) flow moving through a region where an external local magnetic field (magnetic obstacle) is applied and the ordinary ...
Dispersed-phase structure in sheared MHD turbulence
(2012)
Direct numerical simulations are performed to examine particle dispersion in homogeneous turbulence subjected to mean shear and an externally applied magnetic field. We employ the Brucker et al. algorithm for simulating ...
An analytical solution for rapidly distorted turbulent shear flow in a rotating frame
(2006)
In this study we apply rapid distortion theory to the case of nonstratified homogeneous turbulence that is sheared in a frame that counter-rotates at a rate that matches in magnitude the rotation associated with the mean ...
Inertial, viscous and yield stress effects in Bingham fluid filling of a 2-D cavity
(2001)
The present study concentrates on Bingham fluid filling of a 2-D cavity and examines the relative importance of inertial, viscous and yield stress effects on the filling profile. The results presented are obtained using ...
