Differences between single-side and uniform heating for fusion applications
Many international engineering activities are under way to support fusion reactor implementation for the production of economical energy in the distant future. Among the many key technological issues is the development of plasma-facing components for the International Thermonuclear Experimental Reactor (ITER) and the related engineering design activity. Such components will be exposed to single-side (i.e., internal flow channels will be heated externally from one side only) heat flux ranging from 0.1 to 10.0 MW/m{sup 2} over lengths up to 0.3 m. Although other heat-transfer techniques such as liquid-metal and high-velocity-helium cooling are being seriously considered, subcooled flow boiling (with water) is the leading contender for high heat-flux fusion accommodation (HHFFA). Accordingly, interest must be focused on both the local heat transfer and the critical heat-flux (CHF) phenomena. However, irrespective of the convective fluid used (helium, water, or liquid metal) the advantages and adverse consequences associated with single-side heating must be explored and accommodated in future component designs.
