Paper presented at the 5th International Conference on Heat Transfer, Fluid Mechanics and Thermodynamics, South Africa, 1-4 July, 2007.
Under a horizontal temperature gradient along the liquidliquid
interface, the developing processes of thermocapillary
convection in two layers immiscible fluids system absent
gravity were simulated numerically, where the upper layer fluid
was encapsulant B2O3, the underlayer fluid was melting InP in
this paper. The effects of different direction magnetic field on
the developing behaviors of thermocapillary convection were
investigated. The results showed that the flow pattern was
changed obviously and the thermocapillary convection was
damped in some extent and the temperature distributions
became more uniform if magnetic fields in X, Y or Z direction
were applied. Z direction magnetic field had a stronger effect
on the thermocapillary convection and it was enough to
suppress convection significantly at Bz between 0.15T and 0.2T.
The simulation became numerically unstable when Bz was over
