초록

In this research a time dependent thermal and solutal convection was computationally investigated for the physical vapor transport of the mixture of Hg2Cl2-I2 system with for the convective regime from thermal Rayleigh number of 2.16 × 10 6 up to 1.7 × 10 7 with marching time to a steady state problem. With time marching, the convective cells are decreased for the thermal Rayleigh number of 2.16 × 10 6 , and increased for the thermal Rayleigh number of 1.7 × 10 7 . The convective flow structures are found to be essentially time independent on the horizontal orientation of the enclosure with respect to the gravity vector, and on the other hand, time dependent on the vertical orientation of the enclosure with respect to the gravity vector.

Abstract

In this research a time dependent thermal and solutal convection was computationally investigated for the physical vapor transport of the mixture of Hg2Cl2-I2 system with for the convective regime from thermal Rayleigh number of 2.16 × 10 6 up to 1.7 × 10 7 with marching time to a steady state problem. With time marching, the convective cells are decreased for the thermal Rayleigh number of 2.16 × 10 6 , and increased for the thermal Rayleigh number of 1.7 × 10 7 . The convective flow structures are found to be essentially time independent on the horizontal orientation of the enclosure with respect to the gravity vector, and on the other hand, time dependent on the vertical orientation of the enclosure with respect to the gravity vector.
