To avoid the sympathetic vibration, the flow around two circular cylinders with an equal diameter in a tandem arrangement was researched numerically using the finite volume method. Strouhal number as a function of spacing ratio and Reynolds number was investigated. The research results show that the behavior of the Strouhal number with change of the spacing ratio is decided by flow regions, and the effect of the Reynolds number on the Strouhal number has the same trend in all flow regions. The Strouhal number increases with the Reynolds number increasing, but there is a great difference in the increasing amplitude to different flow regions.
