3D Rendering of Jet Forming into Spray

Caption

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. In this image, disturbances propagate through a simulated stream of liquid shortly after it leaves the nozzle in this 3D rendering. The jet begins to deform and then break up into a spray farther downstream.
