Additional information
The two side-by-side cylinders were numerically modelled for a range of pitch to diameter at a Reynolds number of 3000. For the intermediate pitch to diameter ratios multiple shedding frequencies were detected with a biased and bistable wake flow deflection, which intermittently flips over from one side to the other. Phase spectrum of wake revealed that during the flip-over from one stable mode to the other, the intermittent gap vortex shedding was found to be stronger than for a stable mode, with in-phase vortex shedding. For higher pitch ratio cases a symmetrical wake behaviour with anti-phase vortex shedding was observed.
