Spraying efficiently: Breaking up is hard to do

(American Institute of Physics) Using oscillating liquid streams, breakup and drop formation can be improved compared to common straight jets, but dynamic interactions make it difficult for scientists to understand the mechanisms behind this breakup. Now, researchers have simulated the breakup of an oscillating stream using numerical modelings. Their findings, published in Physics of Fluids, give a better understanding of how an oscillating jet achieves these results. The report also offers a way to predict the device's behavior numerically.
