Crimson sophomore Mike Katzer, stole the ball and sent it up the pool to fellow sophomore Kevin DiSilvestro who skipped one off of the water and up into the back right corner...
Fluid dynamics researchers Jacy C. Bird and William D. Ristenpart were doing routine experiments on water droplets, when the supposedly predictable outcome failed to materialize. Instead of coalescing as expected, the charged water drops they were testing began repelling each other—a result that seemed to fly in the face of elementary science...
Last week, they published their accidental discovery that oppositely charged water drops will not stay together in strong electric fields. And the authors say their finding sheds new light on how oil companies, which must condense water droplets as part of the refining process, can operate more efficiently...
...part of the refining process, oil companies use electric fields to separate the oil and water both present when oil is drilled. That process of electrocoalescence, an amped-up version of what naturally occurs with oil and vinegar in salad dressing, uses electric fields to make oppositely charged water drops coalesce with one other, which helps fully separate them from...
...What’s new is that above a critical electric field, the water drops show a direct contact and repel—against what is believed [will happen],” said Bird, a Harvard doctoral student in engineering. Instead of infinitely increasing the coalescing speed of water, an electric field above the critical level causes the drops to deform, combine briefly, and then repel, never actually coalescing...
