Abstract:

The computational fluid dynamics (CFD) simulation of fluid solid coupling heat transfer for the beat transfer properties of Li4Sio4 pebble bed has been performed by referring the actual design parameters in the International Thermonuclear Experimental Reactor (ITER). The thermal hydraulic results under different working conditions are given. Finally, the results of equivalent heat conductivity in pebble bed region obtained with CFD are compared with the related experimental results.
