英文摘要
The steady-state critical heat fluxes (CHFs) in a short SUS304-tube with twisted-tape insert are systematically measured. The SUS304 test tube of inner diameter=6 mm, heated length=59.5 mm, effective length=49.1 mm is used in this work. The SUS304 twisted tapes withtwist ratio=pitch of 180°rotation)/d=2.39, 3.39 and 4.45 are used. The influences of the twisted-tape insert and the swirl velocity on the CHFs are investigated into details and the widely and precisely predictable correlations of the CHFs in the SUS304-tube with twisted-tape insert are given. The correlations can describe the CHFs obtained in this work within -25 to +15 % difference.
