Extract

Vortex shedding is an important factor in the design of structural elements subject to flow induced vibrations. Several reviews have appeared on this topic. However, in model testing, the vortex shedding frequency of a bluff body may change when the model mounting is eccentric (Fig. 1). This has not been studied in detail. Available information in this regard is restricted to the data of Shaw whose tests were conducted in a towing tank.

This technical note presents experimental data on the vortex shedding characteristics of equiangular prisms (Fig. 2) mounted eccentrically in a wind tunnel. Explanations for the possible flow behaviour are also presented.
