2D SiC/SiC composite for flow channel insert (FCI) application

Heat transfer and thermal stress analysis in fluid-structure coupled field

“…PbLi metal fluid in bulk flow and gap flow is considered as incompressible fluid and is governed by N-S equation (1), continuity equation (2), and energy equation (3).…”

“…Many scholars in US, EU, Russia, China, etc have been working together in International Thermal-nuclear Experimental Reactor (ITER) project. In the dual-coolant lithium-lead (DCLL) blanket module concept, flow channel insert (FCI) acts as electrical and thermal insulator between the hot PbLi fluid and the loadbearing structural steel wall [1][2][3]. FCI is usually made of silicon carbide composites.…”

Influence of thermal performance on design parameters of a He/LiPb dual coolant DEMO concept blanket design

“…In order to evaluate the errors induced by the boundary condition 3, a single simulation thermally coupling the fluid domain with the two solid layers (FCI and EU) has been carried out considering k FCI = 1.8 W/mK [6], which results in an equivalent overall heat transport coefficient of about U eq = 309 W/m 2 K. For such simulation, the FCI mesh has 2.7 × 10 5 nodes whereas Eurofer is meshed into 2.8 × 10 5 nodes; the LM mesh is the same as for the single LM domain.…”

“…However, according to Smolentsev et al. [5], the thermal conductivity of SiC FCI (k FCI ) can lay between 1 and 20 W/mK, depending on the fabrication technique, whereas the minimum available depth of the FCI layer (ı FCI ) is 5 mm [6]. The chosen FCI and its depth can alter considerably the thermal behaviour of the blanket.…”

Mechanical and thermal properties of chemical vapor infiltration engineered 2D-woven and 3D-braided carbon silicate composites

“…SiC f /SiC composites are carbon silicate fiber reinforced carbon silicate ceramic matrix materials which have desirable properties for applications in nuclear fusion and advanced fission reactors, such as chemical stability to withstand high temperatures, pseudo-ductile fracture behavior and low induced radioactivity [1][2][3]. SiC f /SiC composites have been considered in the design of nuclear reactors in the USA, Japan and EU, such as the ARIES-AT [4], DREAM [5] and TAURO [6].…”
