Observation of high-speed viscoelastic milk droplet impact to solid surface

Abstract

Skimmed milk powder and water are mixed to make viscoelastic droplets, and a solid surface impact experiment is performed. Observe the droplet impact behavior using a high-speed camera and investigate the influence of the difference of liquid moisture content and the difference of droplet temperature. As a result of the experiment, it became clear that the difference of the moisture content of the droplets influences the presence or absence of attachment. It was confirmed that the effect of droplet moisture content on the contact time was small, but it became clear that increasing the droplet temperature affected the contact time.
