Breakup of Liquid Sheet Analysis when Pressed between Two Gas Streams

Formation of droplets due to breakup of liquid column is important research. In the present study break up of planer liquid sheet has been investigated using linear stability analysis.In this study both sinuous and varicose modes of disturbance are used. As reported by the earlier studies linear analysis of sinuous mode will not create any breakup of the liquid sheet but linear analysis of varicose mode of disturbance can create breakup of the liquid sheet. Also breakup of the liquid sheet is very much nonlinear especially at the time of break up. So a nonlinear analysis is required for the complete understanding of the underlying physics of the breakup process. But which will be the dominant mode of break up process and what will be the frequency and growth rate of fundamental mode of perturbation can be assessed by the linear analysis. So in this study temporal linear stability analysis has been done for both sinuous and varicose modes of disturbance to calculate the growth rate and frequency. The result shows very good agreement with the earlier studies. Parametric studies to understand the influence of fluid velocity ratio, density ratio and surface tension on the growth rate have also been investigated.
