3. Proposed Task 1-3 research projects
Selected to provide the basis for developing practical LM blankets of interest to US and Japan
Fundamental Studies of Flow Dispersal Elements
Manifold (consisting of Rectangular channel(s), Bends, Expansion/Backward facing step, etc. over parameter range)
Insulation techniques for pressure drop (and thermal) control
Technique 1: SiC/SiC or other FCI
Technique 2: Multi-layer ceramic/metallic coatings (or FCI)
Heat and mass transfer studies
Turbulent heat transfer in poorly conducting channels
MHD Mixed convection in fusion blankets
Computational Model Development
High Hartmann number complex geometry simulations
Fundamental turbulence models in different regimes
Transport effects (heat, tritium, corrosion) due to MHD velocity / temperature coupling – towards integrated system modeling and virtual TBM
