Oscillation and atomization process of a liquid film induced by gas flows
Abstract
In nature and many applications, a liquid is atomized by the surrounding gas flow. On the way, gas flow interacts with the liquid, which results in droplets. The spray characteristics of a liquid film by the gas flows are particularly significant because the film break up can generate many tiny droplets. However, the phenomena have not been unclear because of its complicated multi-scale and multi-phase characteristics. As one of the applications, we mainly focus on the atomization process of an air-blasted liquid film, which involves many essences for fluid dynamics and multi-phase flow.
In this presentation for a wide range of audiences, I will briefly explain (1) how the liquid film deformation is caused by the effect of the gas-liquid interaction and (2) how the above deformation process produces droplets with various sizes.

Dr. Ippei Oshima obtained a Ph. D in Engineering at Kobe University, Japan, in 2019. From that year, he worked as a Postdoctoral researcher at Japan Agency for Marine-Earth Science and Technology for two years. In 2021, he moved to Institute of Fluid Science, Tohoku University, as an Assistant Professor.
