Kashinskii, P. Lobanov, A. Kurdyumov, N. Pribaturin] The flow of liquid in an annular channel with a partially shaded flow section is experimentally studied using the electrodiffusion method. The effect on the flow structure produced by a shutter closing one-quarter of the channel cross section is shown. An obstacle installed in the channel causes the flow to attain a 3D structure. The flow pattern in such channel differs significantly from that observed in undisturbed flow moving in an annular channel. It is revealed that the friction stress values measured on the channel's inner wall depend essentially on the azimuth angle over the channel height. With distance away from the obstacle, the influence it has on the hydrodynamic flow structure tends to decrease, but the disturbance produced by it does not die out completely even at a distance of more than 600 mm from the obstacle. Data quantitatively characterizing the disturbance of flow structure in the studied channel are presented.
