LANS Informal Seminar
"Numerical experiments of turbulent flows on supercomputers"

DATE: June 4, 2013

TIME: 13:00:00 - 14:00:00
SPEAKER: Dan Henningson, Director, Swedish e-Science Research Centre
LOCATION: Building 240, 1404-1405, Argonne National Laboratory

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?
