RESUMO

In our previous work we used high-speed imaging to experimentally study the impact of yield-stress fluid drops on pre-coated horizontal surfaces, observing impacts with different drop size, impact velocity, pre-coating thickness, and rheological material properties. Impact events were categorized and a single dimensionless parameter was introduced to reduce the regime map of behavior from four parameters down to one, the ratio of inertial to dissipative forces with proper geometric ratios. Here, we study more deeply the experimental data set, going beyond stick/splash categorization to examine quantitative measures of these impacts. Impact event duration time, material rebound height, maximum radial spread distance, and final crater diameter are presented as a function of the same dimensionless group that reduced the impact regime map. The ratio of inertial to dissipative forces reduces the description of these quantitative parameters and scaling law observations are reported.
