... to occur when the main-drop spacing was five to seven times the jet diameter ( 23 ). Rallison found that drops with a low viscosity achieved a stable shape and were only broken by a high flow rate fluid ( 24 ). On the numerical side, Lee found that the satellite drop volume depended on the wavelength-jet...
