Abstract

The vortex excitation from rectangular elongated plates when the length parallel to the flow is much greater than the height perpendicular to the flow, was studied. Numerical simulations were performed on flows around rectangular plates for chord-thickness ratio varying from 3 to 12 and Reynolds numbers of 200 and 300 based on the plate's thickness. The simulations confirm that the dominant vortex shedding frequency f gradually decreases with increasing c/t and then jumps to higher value. Assuming that vortex shedding has a traveling-wave nature, the results suggest simple considerations for explaining the trend of the Strouhal number to increase stepwise.
