Abstract
The influence of second-order velocity slip of magnetohydrodynamic flow involved in liquid-metal was numerically investigated. A commercial Computational Fluid Dynamics (CFD) code, STAR-CCM+ 13 was used. The MHD flow of Galinstan (GaInSn - Gallium-Indium-Tin) an electrically conducting liquid-metal fluid in the presence of a magnetic field was investigated. The variations of velocity within the second-order velocity slip parameters were found to be influenced by the local variations of the magnetic field. It was determined that the second-order velocity slip persists due to an increase in the thermal boundary layer. The numerical results were compared to published literature and were in good agreement.
