Core of the magnetic obstacle
Votyakov, E. V.; Kassinos, Stavros C. (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 ...

The density of water in carbon nanotubes
Alexiadis, A.; Kassinos, Stavros C. (2008)In this paper, the density of water confined in carbon nanotubes of different sizes and chirality is calculated. Molecular dynamics is used to simulate the spontaneous filling of the nanotube with water molecules coming ...

Diagnostic properties of structure tensors in turbulent flows
Grigoriadis, D. G. E.; Langer, C. A.; Kassinos, Stavros C. (2010)The behavior of turbulence structure tensors based on Large-Eddy Simulations (LES) in a wide range of turbulent channel flows is presented. The structure tensors provide significant physical information on the character ...

Direct numerical simulation of particle laden flow in a human airway bifurcation model
Stylianou, F. S.; Sznitman, J.; Kassinos, Stavros C. (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 ...

Direct numerical simulation of turbulent liquid metal flow entering a magnetic field
Albets-Chico, X.; Grigoriadis, D. G. E.; Votyakov, E. V.; Kassinos, Stavros C. (2013)This paper presents direct numerical simulations (DNS) of fully developed turbulent liquid-metal flow in a circular duct entering a magnetic field. The case of a magnetohydrodynamic flow leaving a strong magnetic field has ...

Direct simulation of the limiting flux: I. Interpretation of the experimental results
Ma, Shengwei; Kassinos, Stavros C.; Fatta-Kassinos, Despo (2009)Using a 2D fully coupled numerical model, the limiting flux phenomenon in the ultrafiltration of dextran was directly simulated assuming neither constant permeate velocity nor constant wall concentrations. It was found ...

Discrete multi-physics simulations of diffusive and convective mass transfer in boundary layers containing motile cilia in lungs
Ariane, M.; Kassinos, Stavros C.; Velaga, S.; Alexiadis, A. (2018)In this paper, the mass transfer coefficient (permeability) of boundary layers containing motile cilia is investigated by means of discrete multi-physics. The idea is to understand the main mechanisms of mass transport ...

Dispersed-phase structural anisotropy in homogeneous magnetohydrodynamic turbulence at low magnetic Reynolds number
Rouson, D. I.; Kassinos, Stavros C.; Moulitsas, I.; Sarris, I. E.; Xu, X. (2008)A new tensor statistic, the dispersed-phase structure dimensionality Dp, is defined to describe the preferred orientation of clusters of discrete bodies. The evolution of Dp is calculated via direct numerical simulations ...

Dispersed-phase structure in sheared MHD turbulence
Xu, X.; Rouson, D. W. I.; Kassinos, Stavros C.; Radhakrishnan, H. (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 ...

The Effect of Flow Rate and Electrostatic Charge on Aerosol Deposition in a Realistic Lung Geometry
Koullapis, P. G.; Kassinos, Stavros C. (Springer International Publishing, 2018)To be able to predict the fate of therapeutic or pollutant xenobiotic inhaled particles in the human lungs, we need to understand the nature of airflow as it occurs throughout the entire respiratory tract.

The effect of flow rate, head position, and inhaler orientation on the airflow and particle deposition in an mri-based mouth-throat geometry
Stylianou, F. S.; Angeli, S.; Kassinos, Stavros C.; Svensson, M. (International Symposium on Turbulence and Shear Flow Phenomena, TSFP10, 2017)The mouth-throat plays a key role in the administration of inhaled medicines. It is an area of intense filtration, where an unacceptably high fraction of the released drug dose is deposited and thus wasted. Due to the ...
