Droplet evaporation is widely present in nature and industrial production, involving heat mass transfer between the droplet surrounding gas environment. This study investigates of individual spherical droplets a high-temperature environment under both stationary forced convection conditions, using theoretical numerical approaches. The results show that established model can effectively reflect temperature change during evaporation. When evaporates gaseous environment, equilibrium influenced by environmental parameters such as humidity. Compared to temperature, humidity has more significant impact on droplet, making it dominant factor affecting temperature. rate air below 0.5, variable-rate aligns closely with simulation (droplet lifetime). above are slightly higher but still have small relative error. As increases, suppressed, leading an increase its lifetime. Establishing appropriate not only deepens our understanding internal mechanisms also provides practical guidance for enhancing droplets.

Newly developed fluid called phase change materials (PCM) used to accumulate solar thermal energy. This paraffin-based is mixed with hybrid nanoparticles composed of titanium dioxide "TiO2″ and copper oxide "CuO". Using this fluid, we hope improve the efficiency industrial installations. A computational dynamics (CFD) model was using Ansys Fluent 19, coupled a home code implemented in C programming language as "user-defined function". Initially, validated against experimental data, then parametric study conducted investigate impact pure paraffin PCM nanoparticles-paraffin PCM, well effect varying mass fraction heat transfer flow rate. geometric parameters such number fins installed storage tank were also considered during analysis. On basis obtained results, it found that incorporation (PCMs) within has potential significantly prolong operational duration systems. Additionally, at 1% concentration increased average temperature by 8% decreased melting time 13.29% compared PCM.
