PREDICTION OF JET BREAKUP LENGTH IN LIQUID-LIQUID SYSTEMS USING THE RAYLEIGH-TOMOTIKA ANALYSIS

A laminar liquid jet in another immiscible liquid call either expand o r contract depending oil the physical properties of the systems. The d iameter of the drops produced as a result of the disintegration of the jet is a function of the jet diameter at the point of breakup. Thus, in order to calculate the drop diameter and interfacial area, it is es sential to have a knowledge of jet breakup length. This article attemp ts to predict jet breakup length in liquid-liquid systems by applying the stability theories by Rayleigh and Tomotika. The effects of small nozzle diameter, nozzle velocity, and viscosity of the continuous phas e on jet breakup length are reported.
