Abstract: A mathematical model is developed with an interest to examine the
effects of the transverse magnetic field on the thermocapillary convection in a
liquid bridge of silicon-oil-based ferrofluid under zero gravity. The mass
conservation level set method is used to capture the motion of the free
surface. The obvious effects of the transverse magnetic field on the flow and
temperature distributions as well as surface deformation are detected. The
transverse magnetic field affects not only the velocity level inside the liquid
bridge but also the velocity level on the free surface. Moreover, the present
results prove that it is necessary to take the surface deformation into account
in the study on the thermocapillary convection.
