      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 ...

      Large Eddy Simulation of near-bed pipelines in oscillatory flow 

      Fonias, E. N.; Grigoriadis, D. G. E. (2018)
      A series of unsteady, three-dimensional numerical simulations of the incompressible, oscillatory flow around a near-bed pipeline is presented. A flow at Reynolds number equal to Reαo=20,000 with respect to the oscillatory ...

      Numerical simulations of turbulent flow in an eccentric annulus of unit eccentricity 

      Kanaris, N.; Albets-Chico, X.; Kassinos, Stavros C. (TSFP-9, 2015)
      In this study, we perform Direct Numerical Simulations (DNS) of fully developed turbulent flows in eccentric annuli having different diameter ratios. Annuli of unit eccentricity, and diameter ratios of 0.2591 and 0.1395 ...

      On the analogy between streamlined magnetic and solid obstacles 

      Votyakov, E. V.; Kassinos, Stavros C. (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 ...

      Three dimensional flow around a circular cylinder confined in a plane channel 

      Kanaris, N.; Grigoriadis, D. G. E.; Kassinos, Stavros C. (2011)
      This paper presents two- and three-dimensional direct numerical simulations of the flow around a circular cylinder placed symmetrically in a plane channel. Results are presented in the Reynolds number range (based on the ...

      Vortex shedding lock-on in a periodic freestream flow past a circular cylinder 

      Olinger, D. J.; Alexandrou, Andreas N.; Dutka, J. (Publ by ASME, 1993)
      Vortex lock-on phenomena in flow past a circular cylinder with a periodic component superimposed on the mean free stream flow is investigated using concepts from dynamical systems (chaos) theory. Numerical results show ...
