Effect of wall roughness on shear viscosity and diffusion in nanochannels
Sofos, F.; Karakasidis, T. E.; Liakopoulos, A. (2010)The effect of wall roughness on liquid argon shear viscosity and diffusion coefficient in nanochannels is studied by non-equilibrium molecular dynamics. Diffusion coefficient results are presented in terms of average values ... -
Fluid Flow at the Nanoscale: How Fluid Properties Deviate from the Bulk
Sofos, F.; Karakasidis, T. E.; Liakopoulos, A. (2013)The studies of fluid flows have been lately transferred to a significant extend at the micro- and the nano-scale, since there is increasing interest in applications that could make possible the construction of systems from ... -
Fluid structure and system dynamics in nanodevices for water desalination
Sofos, F.; Karakasidis, T. E.; Liakopoulos, A. (2015)Nanofluidic applications are currently being investigated in use for water treatment systems as a power efficient and effective means of removing undesirable substances from drinking or sea water. A detailed study of liquid ... -
How wall properties control diffusion in grooved nanochannels: a molecular dynamics study
Sofos, F.; Karakasidis, T. E.; Liakopoulos, A. (2013)The effect of a geometrically-rough wall, amplified by its degree of wettability and stiffness on diffusion coefficient in cases of fluid flow in nanochannels is studied by non-equilibrium molecular dynamics. Diffusion ... -
Molecular dynamics simulation on flows in nano-ribbed and nano-grooved channels
Sofos, F.; Karakasidis, T. E.; Giannakopoulos, A. E.; Liakopoulos, A. (2015)We present molecular dynamics simulation results on fluid and transport properties for nanochannel flows. The upper channel wall is constructed from periodic roughness elements and flows are simulated both in longitudinal ... -
A novel image processing method to determine the nutritional condition of lobsters
Berillis, P.; Simon, C.; Mente, E.; Sofos, F.; Karapanagiotidis, I. T. (2013)The digestive gland of crustacean is involved in various metabolic activities, including the synthesis and secretion of digestive enzymes that begin the process of food digestion, intracellular digestion and absorption of ... -
A quasi-continuum multi-scale theory for self-diffusion and fluid ordering in nanochannel flows
Giannakopoulos, A. E.; Sofos, F.; Karakasidis, T. E.; Liakopoulos, A. (2014)We present a quasi-continuum self-diffusion theory that can capture the ordering effects and the density variations that are predicted by non-equilibrium molecular dynamics (NEMD) in nanochannel flows. A number of properties ... -
Surface wettability effects on flow in rough wall nanochannels
Sofos, F.; Karakasidis, T. E.; Liakopoulos, A. (2012)The effect of rough-wall/fluid interaction on flow in nanochannels is investigated by NEMD. Hydrophobic and hydrophilic surfaces are studied for walls with nearly atomic-size rectangular protrusions and cavities. Our NEMD ... -
Transport properties of liquid argon in krypton nanochannels: Anisotropy and non-homogeneity introduced by the solid walls
Sofos, F.; Karakasidis, T.; Liakopoulos, A. (2009)In this work we calculate the transport properties of liquid argon flowing through a nanochannel formed by krypton walls. Non-equilibrium Molecular dynamics (NEMD) simulations are performed assuming flow conditions ... -
Unified description of size effects of transport properties of liquids flowing in nanochannels
Giannakopoulos, A. E.; Sofos, F.; Karakasidis, T. E.; Liakopoulos, A. (2012)The present work connects transport properties of simple fluids flowing in nanochannels: the diffusion coefficient, the shear viscosity and the thermal conductivity. We used non-equilibrium molecular dynamics (NEMD) ...
