Note (General): To obtain temperature and concentration distributions and to understand convective flow pattern in the case of Traveling Liquidus-Zone (TLZ) method, numerical analyses under various gravity conditions have been carried out. The calculation code is developed based on the Boundary Fitted Coordinate (BFC) method. Quasi-equilibrium state at the interfaces is assumed in order to determine temperature and concentration at the interfaces. By using the developed code, time evolution of temperature, concentration, a stream function, vorticity, and an interface location are obtained. From calculation results, several features are found; (i) the width initially decreases and then begins to increase at a certain time under the higher gravity condition, although the zone width continuously decreases under the lower gravity condition, (ii) supercooling region around axis in the zone can be reduced under the low gravity condition.
