A numerical method of heat transfer for the magnetohydrodynamic flow in the blanket at high Hartmann Number

Heat transfer of magnetohydrodynamic(MHD) flow in rectangular ducts at high Hartmann Number is investigated by numerical simulations. A numerical method is proposed to solve this issue. This method is that the temperature distribution is calculated through the finite volume method, based on the velocity field investigated by a second-order projection method. The numerical results were validated by a power balance method, and showed very good accuracy at Ha~10^3. The simulation results showed that the temperature field is similar to the velocity field, with high temperature at the core and low temperature at the boundary layer. The results may be conductive to investigate the heat transfer characteristics of liquid metal flowing in fusion blanket.
