Effect of the Cavitation in a Nozzle on the Liquid Breakup.

The objective of this study is to promote disintegration of liquid jet by cavitation inside the nozzle. Using cylindrical nozzle, the effects of the nozzle dimensions on the liquid breakup are investigated. When the length-diameter ratio L/D of the nozzle is low, cavitation bubbles are formed inside the nozzle and the breakup of the issuing jet is promoted.
