      Development lengths in Newtonian Poiseuille flows with wall slip 

      Kountouriotis, Zacharias; Philippou, Maria; Georgiou, Georgios C. (2016)
      The effect of wall slip on the development of planar and axisymmetric Newtonian Poiseuille flows is studied by means of finite element simulations. The Navier slip law is employed. i.e., it is assumed that the slip velocity ...

      Effect of head posture on the healthy human carotid bifurcation hemodynamics 

      Papaharilaou, Yannis; Aristokleous, Nicolas; Seimenis, Ioannis; Khozeymeh, M. I.; Georgiou, Georgios C.; Brott, B. C.; Eracleous, Eleni A.; Anayiotos, Andreas S. (2013)
      Head and neck postures may cause morphology changes to the geometry of the carotid bifurcation (CB) that alter the low and oscillating wall shear stress (WSS) regions previously reported as important in the development of ...

      Head posture influences the geometric and hemodynamic features on the healthy human carotid bifurcation 

      Aristokleous, Nicolas; Seimenis, Ioannis; Papaharilaou, Yannis; Khozeymeh, M. I.; Georgiou, Georgios C.; Brott, B. C.; Anayiotos, Andreas S. (2012)
      Atherosclerosis is the third leading cause of morbidity and mortality in the Western world. Low and oscillating wall shear stress (WSS) regions have been previously reported as parameters that correlate with the development ...

      Impact of head rotation on the individualized common carotid flow and carotid bifurcation hemodynamics 

      Aristokleous, Nicolas; Seimenis, Ioannis; Georgiou, Georgios C.; Papaharilaou, Yannis; Brott, B. C.; Nicolaïdes, Andrew N.; Anayiotos, Andreas S. (2014)
      This paper aims at evaluating the changes that head rotation poses on morphological and flow characteristics of the carotid bifurcation (CB) and on the distribution of parameters that are regarded as important in atherosclerosis ...

      Newtonian flow in a triangular duct with slip at the wall 

      Georgiou, Georgios C.; Kaoullas, G. (2013)
      We consider the Newtonian Poiseuille flow in a tube whose cross-section is an equilateral triangle. It is assumed that boundary slip occurs only above a critical value of the wall shear stress, namely the slip yield stress. ...

      Newtonian Poiseuille flows with slip and non-zero slip yield stress 

      Kaoullas, G.; Georgiou, Georgios C. (2013)
      The Newtonian Poiseuille flow is considered for various geometries, under the assumption that wall slip occurs above a critical value of the wall shear stress known as, the slip yield stress. In the axisymmetric and planar ...
