【 摘 要 】

The article presents experimental data on the kinematic structure of flows in circular channels in conditions of dynamical impact on the flow. The experimental data on the influence of dynamical impact by mixing on flow parameters were obtained. Averaged turbulent characteristics were measured at different rotation velocities of mixers and at different distances from them. Optical measurements yielded the profiles of velocities and turbulent characteristics of flows plotted in representative cross sections behind the source of dynamical impacts.To obtain new experimental data on the influence of dynamical impact by mixing on turbulent characteristics of flows, we measured the averaged profiles of streamwise and transverse velocity components, their RMS deviations, and vorticity in different cross sections of the channel (at the distance of 10 and 20 diameters from the system of mixers) at different rotation frequencies of mixers. The measured profiles were then compared with the profiles in undisturbed turbulent flows.
