Tests and computer models were used to study the liquid motion and particulate movement inside dissolving droplets subject to radioactive substances. They demonstrated in this work whether changing its free heat flux may change overall liquid fluid motion somewhere within the droplets and, therefore the depositing patterns of particles on substrates. Imaging Device Elastography (PIV) was used to evaluate the flow motion and particulate pressure gradients within its evaporation droplets. A tiny motile water droplet comprising scattered Styrofoam nanoparticles were used for the studies. Due to the picture correcting difficulty seen in previous quantitative tests using 3D drops, our test was carried out on a comparable cone 2D droplet formed by two quasi-dust particles, whereas the droplet's foot remained sealed. Emission spectra will be used to melt the droplet's upper layer. The radiative cooling of the particle was monitored using strain gauges. During the refining process, the friction factor, and particle concentration profiles, including specific absorption characteristics, were investigated. Researchers then undertook the dynamic analysis of continuous velocity, including radiative models. Its estimated torque profile via buoyant and Marangoni flow accords more with measurements in terms of quality.
