Have you ever experimented with food dye? It can make cooking a lot more fun, and provides a great example of how two fluids can mix together well\u2014or not much at all.<\/p>\n

Add a small droplet in water and you might see it slowly dissolve in the larger liquid. Add a few more drops and perhaps you\u2019ll see a wave of color spread, the colored droplets spreading and breaking apart to diffuse more thoroughly. Add a spoon and begin stirring quickly, and you\u2019ll probably find that the water fully changes color, as desired.<\/p>\n

Researchers at the USC Viterbi School of Engineering, led by Ivan Bermejo-Moreno, assistant professor of aerospace and mechanical engineering, studied a similar phenomenon with gases at high speeds<\/a>, with an eye toward more efficient mixing to support supersonic scramjet engines. In the study, published in Physics of Fluids<\/i>, USC Viterbi Ph.D. Jonas Buchmeier, along with Xiangyu Gao (USC Viterbi Ph.D. \u201820) and former visiting M.Sc. student Alexander Bu\u00dfmann (Technical University Munich), developed a novel tracking method that zoomed in on the fundamentals of how mixing happens. The study helps understand, for example, how injected fuel<\/a> interacts with the surrounding oxidizers (air) in the engine<\/a> to make it operate optimally, or how interstellar gases mix after a supernova explosion to form new stars<\/a>. The method focuses on the geometric and physical properties of the turbulent swirling motions of gases and how they change shape over time as they mix.<\/p>\n","protected":false},"excerpt":{"rendered":"
