摘要

Experiments were performed to ascertain the single-phase heat transfer enhancement provided by streamwise curvature. Curved and straight rectangular flow channels were fabricated with identical 5.0 x2.5 mm cross-sections and 101.6 mm heated lengths in which heat was applied to a 32.3 mm radius concave wall in the curved channel and a side wall in the straight. Reynolds number ranged from 9000 to 130 000 and centripetal acceleration for the curved flow reached 315 times the earth's gravitational acceleration.
