Abstract
In last few decades, although thermal and/or solutal buoyancy-driven recirculating flows in a closed ampoule have been intensively studies as a model problem, there exist interesting total molar flux of Hg2Br2 that have been unreported in the literature. It is concluded that the total molar flux of Hg2Br2(A) increases linearly and directly as the temperature difference regions in the range of 10℃ ≤ ΔT ≤ 50°, 3.5 × 103 ≤ Grt ≤ 4.08 × 103, 4.94 × 104 ≤ Grs ≤ 6.87 × 104. For the range of 10 Torr ≤ PB ≤ 150 Torr, the total molar flux of Hg2Br2(A) decays second order exponentially as the partial pressure of component B (argon as an impurity), PB increases. From the view point of energy transport, the fewer the partial pressure of component B (argon), PB is, the more the energy transport is achieved.
