摘要
Convection in a spherical shell under the influence of a radial force field is an important problem in the geophysical and astrophysical framework. To turn out the earth gravity field which breaks the simulated central force field. such a experiment has to be performed in a microgravity environment. The radial force field is produced by applying a voltage difference between the inner and outer spheres: the dielectrophoretic force. This last field differs from the earth's gravity one. This paper aims at simulating the bifurcated dynamics in this framework. In particular. motions with a 3D structure are presented. The most of simulation results are corroborated by the bifurcation analysis.
