The results of an experimental study of single bubble movement in an upward bubble flow in an inclined flat channel are presented. The measurements were carried out for a liquid Reynolds numbers 2000÷22700 and for channel inclination angles 0÷90. It is shown that in a gas-liquid flow the channel inclination angle has a significant effect on the flow characteristics. The data obtained in the experiments show that bubble rise velocity is lower than that in a large volume of a quiescent liquid and is affected channel inclination angle. With an increase in the Reynolds number, the influence of the channel inclination angle on the two-phase flow decreases.
