The solidification of suspended hollow droplets is a phenomenon commonly encountered in both natural systems and industrial applications. In this study, we investigate the containerless solidification process of hollow droplets subjected to forcing flows, utilizing the front-tracking method - a robust method for simulating multi-phase flow dynamics. Our findings indicate that key parameters, such as the Weber number (We), the solid-to-liquid thermal conductivity ratio (ksl), and the gas-to-solid viscosity ratio (μgl), have a impact on both the solidification rate of the advancing front and the final geometric characteristics of the droplets. The inner (Ari) and outer (Aro) aspect ratios of the droplets are strongly influenced by these parameters during the solidification process. The study covers a wide range of parameter values, with We varying from 0.125 to 4, ksl ranging from 0.125 to 4, and μgl spanning from 0.0125 to 0.4. By analyzing the effects of these parameters, we provide deeper insights into the complex interplay of thermal and flow properties that govern the solidification process. These results not only enhance our understanding of phase change mechanisms in containerless environments but also offer valuable implications for material processing and the development of advanced manufacturing technologies.
