Abstract

Abstract:

Three-dimensional simulation on conjugate heat transfer in fluid-structure coupled field is carried out. The calculation model is built for the dual-cooled lithium-lead blanket, which is the key technology of international thermonuclear experimental reactor. The effects of thermal conductivity of FCI material SiC and the convection heat transfer coefficient on temperature field are analyzed. The results show that temperature gradients and thermal stresses decrease when the material has good thermal conductivity. High convection heat transfer coefficient results in lower temperature and decrease in thermal deformation.

Key words: fusion reaction, FCI, fluid-structure interaction, temperature field, thermal stress
