Study of gas-saturated turbulent streams using a laser doppler velocity meter

New experimental results on the study of a turbulent gas-saturated stream in a tube using a laser Doppler velocity meter and a thermoanemometer are discussed. The distributions of the volumetric gas content over the cross section of the tube and profiles of the average velocities and average and pulsation characteristics of the shear stress at the wall in the stream under investigation are obtained. The experimental apparatus and the method of the measurements are described.
