Abstracts:
The dependencies of departure bubble diameter on liquid velocity and gas flow rate through the capillary inserted into the liquid flow in a 10x10 mm channel are obtained. The bubble departure frequency was estimated. The effect of bubble production mode on the distribution of bubble size in the flow is discussed. |
