Description
After a short description about the activities of the Swedish
e-Science Research Centre (SeRC) a general motivation of
studying turbulence is given, including elucidating the large
range of scales needed to be resolved for high Reynolds
numbers. The infrastructure needed to perform these
simulations are discussed, including the simulation codes
and large scale computational resources. Examples of such
large scale simulations are then
given in terms of high Reynolds number turbulent boundary
layers on a flat
plate, and also such a boundary layer with an obstacle.
Finally the
possibility to scale up the simulations to flows of direct
aeronautical
interest is discussed, e.g. when will it be possible to replace
typical
university wind tunnel experiments with DNS? This begs
the question of the
possibility of exa-scale computing and questions if the
current methods can
be used on such e-Infrastructure is posed?
