Predicted thermal-hydraulic characteristics of cable-in-conduit conductor windings during steady-state operation
- Westinghouse Electric Corp., Pittsburgh, PA (United States)
A finite difference numerical model is developed to simulate steady-state supercritical helium flow and heat transfer within superconducting magnets using double-pancake coils of cable-in-conduit conductor (CICC). The model is implemented in computer programs which calculate global temperature and pressure distributions in winding packs subjected to time-averaged thermal loads. These programs are used to predict nuclear heating effects upon pressure drop and temperature rise along the forced-flow cooled superconductors of magnets in the Toroidal Physics experiment (TPX) tokamak. The authors present results suggesting superconductor temperature margin depends upon how effectively a coil design {open_quotes}surfs{close_quotes} the helium heat capacity {open_quotes}wave{close_quotes} and case-to-coil heat transfer interactions.
