Demokratis Gregoriades


“Demokritos” (Greece) initially working on environmental flows and later on computational and experimental nuclear thermal-hydraulics at the GRR-1 reactor. Received his PhD (2003) in Mechanical Engineering from the Aristotle University of Thessaloniki (Greece) on “Large Eddy simulations of turbulent flows in complicated geometries”. He joined the university of Cyprus in 2006 as member of the Ucy-CompSci group. Dr. Dimokratis Grigoriadis received his B.Sc. (1995) in Mechanical Engineering at UMIST (Manchester, UK) and his M.Sc. (1996) in Environmental and applied Fluid Dynamics from the Von Karman Institute for Fluid Dynamics (Belgium). In 1996 he joined the National Research Center.

Research Interest

His research interests include environmental fluid dynamics, incompressible turbulent flows in classical hydrodynamics and magnetohydrodynamics (MHD), oscillating and pulsating turbulent flows, multiphase flows and atmospheric dispersion, flows in coastal regions, Ejection events and Lambda structure in an ascillatory flow... Heat transfer and storage in turbulent flows. His current research interests focus on basic heat and mass transport phenomena using advanced and efficient numerical techniques such as the immersed boundary method for Large Eddy Simulations (LES) and Direct Numerical Simulations (DNS).
