In turbulent flow, the normal procedure has been to seek means u of the fluid velocity u rather than the velocity itself. If these means are defined by local spacial averaging with an averaging radius of โฆ the approach is known as large eddy ลฝ . simulation, and u denotes the eddies of size 0 โฆ and l
The turbulent flow past a circular cylinder (Re=3900) was computed by large eddy simulation (LES). The objective was not to investigate the physical phenomena of this flow in detail but to study numerical and modeling aspects which influence the quality of LES solutions. Concerning the numerical met
