Abstract
Break-up phenomena of liquid drops impacting on immiscible liquids have been investigated. Oscillation of falling drops was found to play an important role in break-up in a certain range of falling height. Criteria for break-up were discussed, and it was found that either Reynolds or Weber number was not adequate in describing the criteria of break-up of a liquid drop impacting on an immiscible liquid target. From the experimental results of the present study, empirical models have been formulated, which enables to predict the critical falling height for the first break-up of a drop. Conditions for break-up of liquid iron drops impacting on a liquid slag were predicted using the models. The prediction showed that the majority of metal drops propelled to the top space of an intensive reactor should suffer break-up during the fall through the slag layer.
