Understanding droplet-particle collisions is critical for regulating spray coating processes.
Existing studies mainly focused on collision between a single component droplet and a …

We study the vertical impact of a droplet onto a cubic pillar of comparable size placed on a
flat surface, by means of numerical simulations and experiments. Strikingly, during the …

We experimentally observe a new phenomenon, the formation of a toroidal region of lower
film thickness in the center of the lamella formed during high Weber number water droplet …

The influence of surface roughness, especially regularly patterned micro-structures on the
physical outcomes of droplet impacts, is far from fully understood. In order to get a deeper …

The spreading of the water droplets falling on surfaces with a contact angle from 0 to 160°
was investigated in this work. Superhydrophilicity of the surface is achieved by laser …

The phenomenon of bubble encapsulation results from droplet impact on a liquid film for
specific impact conditions, but there is no established criterion for predicting its onset …

Hypothesis: The shape of the wetted region after a droplet impact can vary significantly even
in the early phase of the process. How much of the early spreading process occurs within …

The experimental results of the water droplet impact on the tilted metal substrates are given.
To establish the effect of the texture on the spreading of droplets, parallel-directed scratches …

This paper introduces Interface Equilibrator (IE), a new graphical-user-interface software for
simulating the equilibrium shape of fluid–fluid interfaces in a wide range of wetting and …

This study shows that the LASER Pattern Shift Method (LPSM) is a powerful measurement
technique for film thickness measurements. In this paper, the approach of the LPSM is …
