The Effect of the Angle of Pipe Inclination on the Average Size and Velocity of Gas Bubbles Injected from a Capillary into a Liquid

This work is devoted to an experimental study of the effect coalescence on average diameter and velocity gas bubbles in inclined pipe. The measurements were carried out for agas flow rate 3.3 5 mL/min at pipe inclination angles 30–60°. bubble diameters was performed using a shadow photography method. values obtained depending angle A map regime parameters constructed which form stable structure—a chain with equal diameter.
