Abstract
The relationship between the vortex shedding from the surface of three row circular cylinders of the same diameter in staggered arrangement and the ratio of pitch to diameter or void fraction is experimentally investigated. The results show that periodical vortex shedding happens when the void fraction is no more than 0.14. As the ratio of transverse pitch to diameter is no more than 2.0, gap flow is bistable deflective flow. But bistable deflective flow disappears as the ratio more than 2.0. Strouhal number in two-phase flow reduces with the increase of the void fraction.
