Dense Suspension Splat: Monolayer Spreading and Hole Formation After Impact
Luuk A. Lubbers, Qin Xu, Sam Wilken +2
We use experiments and minimal numerical models to investigate the rapidly expanding monolayer formed by the impact of a dense suspension drop against a smooth solid surface. The e…
Splashing onset in dense suspension droplets
Ivo R. Peters, Qin Xu, Heinrich M. Jaeger
We investigate the impact of droplets of dense suspensions onto a solid substrate. We show that a global hydrodynamic balance is unable to predict the splash onset and propose to r…
Impact Dynamics of Oxidized Liquid Metal Drops
Qin Xu, Eric Brown, Heinrich M. Jaeger
With exposure to air, many liquid metals spontaneously generate an oxide layer on their surface. In oscillatory rheological tests, this skin is found to introduce a yield stress th…
Effect of oxidation on the Mechanical Properties of Liquid Gallium and Eutectic Gallium-Indium
Qin Xu, Nikolai Qudalov, Qiti Guo +2
Liquid metals exhibit remarkable mechanical properties, in particular large surface tension and low viscosity. However, these properties are greatly affected by oxidation when expo…
