Vortex street
The experiments were conducted to measure the velocities of flow around a circurlar cone. Because of variaton of the cross section area in the longitudinal axis, the flow around the the circular cone behaves very high complex and forms the vortex streets which are issued from both side of the cone and attach in downstream to the plate setting it. The flow fields were visualized using the mixed particles in water and resulted in the velocity fields by the method of Particle Imaging Velocimetry (PIV). From analyses of the instantaneous velocity fields, the Strouhal numbers which showed an interesting variation were gained to the Reynolds numbers.
