Abstract

The hypervapotron (HV) has been demonstrated to be a superior thermal management (TM) and high heat flux removal (HHFR) technique for fusion reactor plasma-facing component applications involving a single-side absorbed heat flux (up to between 20 and 30 MW/m2). However, the conjugate heat transfer HV flow channel (HVFC) performance only can be optimized completely when the related HHFR controlling parameters have been identified. In an earlier work, Part I of the present effort identified four HV controlling TM and HHFR dimensionless parameters. In the present work, four additional dimensionless primary controlling parameters and five secondary controlling parameters have been identified. The controlling parameters include effects of: (1) most geometric specifications of the array of fins; (2) variations in the HV wall thermal conductivity and heat transfer coefficient; (3) effective Biot numbers charactering two-dimensional effects which include the fin array, a typical fin, and the vertical side wall; (4) HVFC unobstructive portion flow aspect ratio, and (5) the HVFC wall aspect ratio. Future work should assess the sensitivity of these parameters.
