The influence of temporal heating modulation on non-isothermal floating droplet dynamics

The action of temporal heating modulation on Marangoni flows in a droplet on a liquid substrate is investigated. The problem is studied numerically in the framework of long-wave amplitude equations and precursor model. It is shown that temporal modulation can lead to a change of the droplet shape. Specifically, rhombic droplets have been obtained. A modulated cooling from below can lead to periodic or quasiperiodic oscillations or the droplet's decomposition.

Automated summary

This study investigates the effect of temporal heating modulation on Marangoni flows in a droplet on a liquid substrate. The numerical simulations, based on long-wave amplitude equations and precursor model, demonstrate that temporal modulation can induce shape changes in the droplet, resulting in the formation of rhombic droplets. Additionally, modulated cooling from below can lead to periodic or quasiperiodic oscillations, or even the decomposition of the droplet.
