First-wall fusion-blanket heat transfer

PDF Version Also Available for Download.

Description

To accommodate the high heat flux and neutron and gamma heat generation in the first wall of a fusion reactor, an array of tubes or tube-bank forms a first wall shield of the blanket. A series solution to the two-dimensional (in r,theta coordinates), time-dependent heat conduction equation has been found in terms of Fourier-Bessel (modified Bessel) functions. Steady-state solutions are found as limiting solutions. The heat sources are pulsed on and off to simulate the plasma burn and cool down periods. In addition to the Biot numbers, the time-dependent solution is given in terms of the Fourier, Pomerantsev, and Kirpichev ... continued below

Description

To accommodate the high heat flux and neutron and gamma heat generation in the first wall of a fusion reactor, an array of tubes or tube-bank forms a first wall shield of the blanket. A series solution to the two-dimensional (in r,theta coordinates), time-dependent heat conduction equation has been found in terms of Fourier-Bessel (modified Bessel) functions. Steady-state solutions are found as limiting solutions. The heat sources are pulsed on and off to simulate the plasma burn and cool down periods. In addition to the Biot numbers, the time-dependent solution is given in terms of the Fourier, Pomerantsev, and Kirpichev numbers and numerically evaluated for a wide range of plasma and first wall conditions. Comparison of the thermal responses of the first wall between aluminum, a high thermal conductivity material and stainless steel, a low thermal conductivity material, is made.
