  • By applying Digital Particle Image Velocimetry (DPIV) technique,velocity fields in the near wakes behind semicircular and sinusoidal shaped peninsulas in constant inlet flow are measured in detail respectively,and a large number of quantitative data are acquired.This paper puts enough emphasis on the similarity in analyzing the mean velocity over a long period of time (where the long period is referred to as a cycle of the Karman Vortex Shedding).In this way we attempt to find out some disciplines of the velocity distribution in this region.The averaged velocity distribution in each transect seems to approximately obey the similarity law after normalization,but the turbulent parameters distributions are quite different.
