This vortex street was much different with that of flow around long squire cylinder. With further analysis on the turbulent kinetic energy, distribution of spectrum energy and average velocity of the wake after short squire cylinder, it was found that the low oscillation frequency corresponding to the main flow field is lower than that of long squire cylinder. With basic physical parameters (velocity, vorticity, drag coefficient, lift coefficient and average statistics) analysis, the initial position where the two vortexes merged and the interaction region were ascertained. It was found that the minimum average velocity in vertical direction and the strongest turbulent flow field pulsating energy appeared in this merge zone.
