Abstract
It is well established now that large scale coherent structures are essential features of turbulent shear flows. These structures can be observed and have been detected by means of visual studies. However, extended quantitative investigations rely on measurements at isolated locations in most cases. Then the problem arises that the information pertaining to the investigated structures has to be extracted from time records of the velocity or of other quantities like wall shear stress or pressure. For this purpose detection schemes have been invented in order to fix the instances when structures pass the probe. Sometimes conditional averaging is used to reconstruct the flow field associated with the structure.
