Abstract: The dynamics characteristics of dual bluff body vortex and the best structure of dual bluff body vortex improving fluid oscillation are studied. The experiment educes the result of different structure of dual bluff body Strouhal number curve;the result indicates dual bluff body’s Stroutal number is constant. The experiment on f 50 flowmeter proves:Dual bluffbody can receive idea vortex superpose on some condition and improve fluid oscillation. On axis symmetry point,the wave of fluid oscillation have same amplitude and 180° angle discrepancy. A new type vortex flowmeter by using the dual bluff body and differential sensor technology is developed.

Key words: Dual bluff body vortex, Fluid oscillation, Vortex flowmeter
