Further investigation on a practical applications of the Karman vortex flow meter were studied. In this experiments, the effects of a distance between two parallel side plates of a Karman vortex shedding from cylinders with three shapes of cross-sections were investigated. The three types of cross-section were (1) circular type, (2) semi-circular type and (3) semicircular with plate which is effective to stabilize the vortex shedding.
Within the limits of this experiment, the shedding frequency of the vortex were reduced by the groth of the boundary layers of each side plate, and a characteristic flow patterns were observed by the flow visualizations.
