S051052 Magnetic force effect between vertically situated 2 solenoidal coils on Rayleigh-Benard convection of water in a shallow cylindrical vessel

Abstract

We numerically examined the induction of spoke pattern on Rayleigh-Benard convection(diameter/vessel height=10, Pr=6.0, Ra=1.0x10^4) varying the vertical and redial components of magnetic force. We investigated the influenceof the magnetic force by using 2 turns coil as well as the actual conventional magnet of 1800 turns coil. As the results, the radial component was found to be so important to induce the spoke pattern on convection.
