Drop formation from cylindrical jets in immiscible liquid systems

Abstract A theoretical analysis is presented for predicting the size of drops formed from a laminar cylindrical jet when one Newtonian liquid is injected through a nozzle into a second immiscible Newtonian liquid. The analysis couples stability theory with the requirement that the disturbances travel at the same velocity as the jet interface. Comparison of the theory with experimental data for thirteen mutually saturated liquid‐liquid systems covering a wide range of physical properties shows a mean error of 11.7% in prediction of the specific surface.
