The dynamics characteristics of dual bluff body vortex and the best structure of dual bluff body vortex improving fluid oscillation are studied.

At the same time, the experimental results show that the method of the isolate elasticity has little effect on the anti-jamming performance of the dual bluff body vortex flowmeter.

We made the flow visualization experiment for flow over bluff body or dual bluff body to study the characteristics of vortex shedding.
