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 ...

Three-Dimensional Modelling of Concentration Fluctuations in Complicated Geometry
Andronopoulos, S.; Grigoriadis, D. G. E.; Robins, A.; Venetsanos, A.; Rafailidis, S.; Bartzis, J. G. (2001)The strong fluctuating component in the measured concentration time series of a dispersing gaseous pollutant in the atmospheric boundary layer, and the hazard level associated to short-term concentration levels, demonstrate ...
