A Close-up on OsciJet’s Ingenious Spray Formation
How does the OsciJet nozzle gain its performance? To get to he bottom of this question, a joint collaboration of the TU Berlin and FDX Fluid Dynamix GmbH performed high fidelity experiments and simulations to reveal the physical mechanisms that lead to breakup and droplet formation of a liquid stream emanating from the nozzle. As for all sorts of sprays, the development hydrodynamic instabilities play are a critical part in the breakup process as they lead to the destabilization of the liquid surface of the stream. In the OsciJet spray, the development of these instabilities is amplified by the oscillation the nozzle produces. This helps to effectively atomize the liquid into droplets and spread them over a wide area.
