Flow boiling critical heat flux enhancement in ZrSi2 accident-tolerant fuel cladding with porous structures

Advances in micro and nanoengineered surfaces for enhancing boiling and condensation heat transfer: a review

“…Coatings with high thermal conductivity can improve performance. 146 Interconnected pores formed through structure fabrication also leads to enhanced wicking 149,150 and can increase lm evaporation contributions as well as bubble departure frequency. A laser-induced uorescence technique with 1 mm diameter tracer particles has been used to characterize liquid velocity inside pores.…”

Joining SiC ceramics with ZrSi2–SiC filler at low temperatures

“…15 In addition, ZrSi 2 is considered as a candidate material for nuclear energy application due to its low neutron cross-section. 16 However, the difference in thermal expansion coefficient between ZrSi 2 (8.3 × 10 −6 / • C) 17 and SiC (4 × 10 −6 / • C) 18 ceramics could lead to the generation of a high residual stress in the joint after cooling, which potentially weakens the mechanical performance of the joint. Generally, materials with low thermal expansion coefficient can be added to reduce the thermal expansion coefficient mismatch between the interlayer and the substrate [19][20][21] in order to improve the joint performance.…”

“…The ZrO 2 ceramic has a melting point of 2988 K, which is known to have a wide range of applications in the field of oxidation‐resistant coating 15 . In addition, ZrSi 2 is considered as a candidate material for nuclear energy application due to its low neutron cross‐section 16 . However, the difference in thermal expansion coefficient between ZrSi 2 (8.3 × 10 −6 /°C) 17 and SiC (4 × 10 −6 /°C) 18 ceramics could lead to the generation of a high residual stress in the joint after cooling, which potentially weakens the mechanical performance of the joint.…”
