Detailed numerical analysis of heat transfer in a water-cooling first wall was carried out based on the conceptual design of CFETR WCSB blanket.
Investigation of the influences of buoyancy effect and surface roughness on heat transfer in the water-cooling first wall was presented.
Analysis of the effect of the front wall thickness on temperature was carried out for the water-cooling first wall design.
Simulation results of two 1D CFD methods were evaluated by the 3D CFD data.
