Abstract
A qualitative difference between dynamics of the inner regions of vortex pairs with one-way and opposite rotation of elements is shown experimentally. Typical spatial scales of vortex clusters with two elements and velocity distribution inside them were determined. Experiments were carried out in the air jets using hot-wire probe equipment with a block for registration of the evolution phase of nonstationary vortex structures. It was shown that the well-known formulas for dipole and quadrupole vortices may be used for description of velocity distribution.
