Breakers of liquid drops

Includes bibliographical references (pages 104-105)An experimental study has been performed to study incipient\ud drop breakup for several liquids and impact liquid film\ud thicknesses. The study was conducted to determine the relationship\ud between the incipient Reynolds number (Re), Weber number (We), and\ud the dimensionless film thickness ( b*) at breakup. The\ud experimental results conclude that the incipient breakup of liquid\ud drops impacting on thin liquid films may be correlated using the\ud Re, We and b*?? Depending on the liquid properties and the\ud dimensionless film thickness, the incipient breakup tends to become\ud independent of the Reynolds numbers at high Weber numbers, and\ud becomes very dependent on the Reynolds number at low Weber numbers.\ud Above some critical dimensionless film thickness (measurements give\ud the value of b * = .5), the incipient Reynolds number and the\ud Weber number decrease with an increase of the film thickness.
