【 摘 要 】

The subcritical flow regime of Reynolds number Re = 1.0 x 104is the subject of the paper in the context of aerodynamic interference of tandem circle cylinders. The two cylinders are in distance of L/D equal to 2.0. The purpose of the paper is to determine aerodynamic drag and lift coefficients and the frequencies for upstream and downstream cylinders and also the distribution of the velocity around the cylinders and in their wakes. In numerical analysis the RNG k - method was used.
