[MIS27-P02] Axial flow characteristics of a liquid metal roll convection under a horizontal magnetic field
Keywords:Natural convection, Magnetic field, Flow transition
We examined axial flow and advection structures on quasi-two-dimensional convection rolls by laboratory experiment using liquid metal layer imposed by horizontal magnetic field. Ultrasonic velocity profiler visualized and quantified roll structures and axial flows by multiple measurement lines set in the fluid layer. The measurements were performed for different Rayleigh and Chandrasekhar numbers and variations of the axial flow velocity were investigated. Visualized flow pattern suggested influence of Lorenz force on the axial flow and scaling law with considering the Lorenz force effect was discussed.
