      Efficient treatment of complex geometries for large eddy simulations of turbulent flows 

      Grigoriadis, D. G. E.; Bartzis, J. G.; Goulas, A. (2004)
      Incompressible turbulent flow over a backward facing step at Reh=5100 is investigated by large eddy simulations (LES). The ratio of the oncoming boundary layer thickness δ to the step height h was set to 1.2. Additionally ...

      LES of the flow past a rectangular cylinder using the immersed boundary concept 

      Grigoriadis, D. G. E.; Bartzis, J. G.; Goulas, A. (2003)
      Incompressible turbulent flow past a long square cylinder is investigated using large eddy simulations LES). Results are presented and compared with available experimental databases for a Reynolds number Red = 22 000. The ...

      Performance and stability bounds for dynamic networks 

      Koukopoulos, D.; Mavronicolas, Marios; Spirakis, Paul G. (2007)
      In this work, we study the impact of dynamically changing link capacities on the delay bounds of LIS (Longest-In-System) and SIS (Shortest-In-System) protocols on specific networks (that can be modelled as Directed Acyclic ...
