Flow of Aqueous Solutions in Carbon Nanotubes
Kassinos, Stavros C.; Walther, J. H.; Kotsalis, E.; Koumoutsakos, P. (Springer Berlin Heidelberg, 2004)We conduct simulations of water flowing inside carbon nanotubes using non-equilibrium molecular dynamics simulations. A new adaptive forcing scheme is proposed to enforce a mean center of mass velocity. This scheme is ...

Full magnetohydrodynamic solution of liquid-metal flow in an insulating pipe subjected to a strong fringing magnetic field
Albets-Chico, X.; Radhakrishnan, H.; Kassinos, Stavros C. (2012)This paper addresses liquid-metal flow under a strong, fringing, decreasing magnetic field in an insulating circular pipe by a full resolution of the magnetohydrodynamic (MHD) equations. The aims of the paper are first to ...

Fully turbulent flow in a physiologically realistic human airway bifurcation
Stylianou, F. S.; Kassinos, Stavros C. (TSFP-9, 2015)Recent computational studies have shown that the airflow in the upper human airways is turbulent during much of the respiratory cycle. A feature of respiratory airflow that poses a challenge to computations based on ...

A general framework for computing the turbulence structure tensors
Stylianou, F. S.; Pecnik, R.; Kassinos, Stavros C. (2015)Good measures of the turbulence structure are important for turbulence modeling, flow diagnostics and analysis. Structure information is complementary to the componentality anisotropy that the Reynolds stress tensor carries, ...

A grid-free abstraction of the Navier-Stokes equations in Fortran 95/2003
Rouson, D. W. I.; Rosenberg, R.; Xu, X.; Moulitsas, I.; Kassinos, Stavros C. (2008)Computational complexity theory inspires a grid-free abstraction of the Navier-Stokes equations in Fortran 95/2003. A novel complexity analysis estimates that structured programming time grows at least quadratically with ...

Immersed boundary method for the MHD flows of liquid metals
Grigoriadis, D. G. E.; Kassinos, Stavros C.; Votyakov, E. V. (2009)Wall-bounded magnetohydrodynamic (MHD hereafter) flows are of great theoretical and practical interest. Even for laminar cases, MHD simulations are associated with very high computational cost due to the resolution ...

In silico assessment of mouth-throat effects on regional deposition in the upper tracheobronchial airways
Koullapis, P. G.; Nicolaou, L.; Kassinos, Stavros C. (2018)Regional deposition of inhaled medicines is a valuable metric of effectiveness in drug delivery applications to the lung. In silico methods are now emerging as a valuable tool for the detailed description of localized ...

Influence of water model and nanotube rigidity on the density of water in carbon nanotubes
Alexiadis, A.; Kassinos, Stavros C. (2008)The density of water calculated through molecular dynamic simulations using different water models and rigid/flexible carbon nanotubes is studied. A previous equation, determined in an earlier work in order to correlate ...

Lagrangian particle dispersion in turbulent flow over a wall mounted obstacle
Grigoriadis, D. G. E.; Kassinos, Stavros C. (2009)Large-eddy simulations (LES) of particle-laden turbulent flows are presented in order to investigate the effects of particle response time on the dispersion patterns of a space developing flow with an obstruction, where ...

Large-eddy simulations of the turbulent Hartmann flow close to the transitional regime
Sarris, I. E.; Kassinos, Stavros C.; Carati, D. (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 ...

Linear analysis of generalized turbulent hyperbolic flow in a rotating frame
Langer, C. A.; Akylas, Evaggelos; Kassinos, Stavros C. (2007)We apply inviscid rapid distortion theory to the generalized case of turbulent hyperbolic flow in a rotating frame and investigate the dependence of the evolution of the turbulent kinetic energy on the frame rotation rate. ...

Linear dependencies in fourth-rank turbulence tensor models
Reynolds, W. C.; Kassinos, Stavros C. (1998)In turbulence modeling, and perhaps elsewhere, one encounters the need to model a fourth-rank tensor Mijpq, which is symmetric in ij and pq, in terms of a second-rank symmetric tensor bij. It has commonly been assumed that ...

Magnetohydrodynamic turbulence at moderate magnetic Reynolds number
Knaepen, B.; Kassinos, Stavros C.; Carati, D. (2004)We consider the case of homogeneous turbulence in a conducting fluid that is exposed to a uniform external magnetic field at low to moderate magnetic Reynolds numbers (by moderate we mean here values as high as 20). When ...

MHD flow past a circular cylinder using the immersed boundary method
Grigoriadis, D. G. E.; Sarris, I. E.; Kassinos, Stavros C. (2010)The immersed boundary method (IB hereafter) is an efficient numerical methodology for treating purely hydrodynamic flows in geometrically complicated flow-domains. Recently Grigoriadis et als. [1] proposed an extension of ...
