- Description
- In this study the interaction of two parallel 20% NaCl solution jets in immiscible oil was studied experimentally. In particular, the jet separation distance, breakup length and resultant droplet diameter was measured as a function of initial nozzle separation distance and jet volumetric flow rate. It was found that for the flow rates investigated at each nozzle separation distance the two jets moved closer to each other and eventually reached an equilibrium separation distance that was approximately 70 % of the spacing between the two nozzles. The distance along the jet surface from the nozzle where instabilities were first observed on the surface of the jet was also a function of the initial separation distance and only weakly dependent on the jet flow rate. The jet breakup length and resultant droplet diameter were both influenced by flow rate and nozzle separation distance, with breakup length decreasing with decreasing nozzle spacing at the higher flow rates. Interestingly, a linear relationship between droplet diameter and breakup length was found that was largely independent of nozzle spacing and consist with conventional Rayleigh jet breakup theory. The implications of the experimental observations on the design of multi-jet systems are discussed.
