Abstract

A series of large-eddy simulations of a turbulent asymptotic suction boundary layer (TASBL) was performed in a periodic domain, on which uniform suction was applied over a flat plate. The Reynolds number (defined as the ratio between free-stream and suction velocity) was Re=333 and a variety of domain sizes were considered in temporal simulations in order to investigate the effect of the computational domain size and temporal development length. The asymptotic state is related to high friction Reynolds numbers and was found to require large computational domains and development lengths.
