Efficient treatment of complex geometries for large eddy simulations of turbulent flows
(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 ...
Large-eddy simulations of unidirectional water flow over dunes
(2009)
The unidirectional, subcritical flow over fixed dunes is studied numerically using large-eddy simulation, while the immersed boundary method is implemented to incorporate the bed geometry. Results are presented for a typical ...
