The results of an experimental study of bubble diameters variation with distance from the point of gas injection in an upward bubble flow in an inclined flat channel are presented. The measurements were carried out for a superficial fluid velocity of 0.51 m/s (Re=12400) and at various values of the gas flow rate ratio. It is shown that at small values of the gas flow rate ratio ( β <2%), the coalescence of bubbles is practically absent, therefore the angle of inclination of the channel and the distance from the point of introduction of gas into the liquid flow do not affect the average diameter of gas bubbles.
