AB - In this study, as the expectation ratio Ar increases, the internal convective velocity |U|max decreases sharply due to the expansion of wall frictional resistance. This lowers the heat and mass transfer efficiency (Nu, Sh) at the crystal growth interface to its lowest level, ultimately causing an exponential decrease in the single-crystal growth rate of mercury(I) bromide (Hg₂Br₂). To efficiently manufacture high-speed and high-quality mercury(I) bromide crystals, it is essential to design low expectation ratio Ar ampoules and optimize the process to ensure appropriate convective intensity within a range that does not induce convective instability. The results of this study are expected to serve as important basic computational data for designing constricted diffusion systems under microgravity or terrestrial conditions, such as in future Korean Spaceflight.
