Droplet impinging behavior on surfaces Part i - Hydrogen Peroxide on Aluminium Surface

Abstract

In the present work the droplet behavior of the hydrogen peroxide (6% by weight) on a aluminum surface is reported. The behavior of hydrogen peroxide droplet is compared with water droplet for the same temperature conditions. Visualization of the droplet falling on a aluminum surface is done using a high speed camera. A data acquisition system is used for measuring the real time temperature. The characterization of droplet dynamics with variation in temperatures is detailed. The results reveal that with increase in temperature, the droplet splashes in to the ambient like a jet which is unlike water behavior, which when subjected to the same temperature conditions. The behavior of water droplet and hydrogen peroxide droplet after impinging and spreading over the surface and evaporation phenomenon is studied and observed.
