DETERMINATION OF VORTEX CONVECTION VELOCITY WITH APPLICATION OF FLOW VISUALIZATION AND IMAGE PROCESSING

Grzegorz L. Pankanin, Artur Kulinczak

Abstract

The paper is related to von Karman vortex shedding phenomenon being the basis of the vortex flow meter design. The vortex convection velocity belongs to the problems rather rarely touched on in papers and articles. But its recognition can improve our knowledge concerned the applied phenomenon and finally help in its better understanding. Due to the flow visualization supported by the image processing, tracking of the vortices is feasible. Finally, the convection velocity can be calculated and its changeability along the pipe axis can be evaluated.
