WebMar 13, 2011 · Liquid drop impacts on a smooth surface were studied at elevated chamber pressures to characterize the effect of gas pressure on drop spreading and splashing. Five common liquids were tested at impact speeds between 1.0 and 3.5 m/s and pressure up to 12 bars. Based on experiments at atmospheric pressure, a modification to the “free … WebMay 31, 2007 · Splashing occurs when a liquid drop hits a dry solid surface at high velocity. We report experimental studies of how the splash depends on the roughness and the texture of the surfaces as well as the viscosity of the liquid. For smooth surfaces, there is a ``corona'' splash caused by the presence of air surrounding the drop. There are … lehigh valley health network gynecologist
