Forced-convection heat transfer to superheated steam in turbulent flow was experimentally investigated, utilizing two-channel geometries: a round tube, 0.333-in. ID by 12.00 in., and a thin rectangular channel, 0.047-in. wide, aspect ratio, 26.6: 1, and 12.00 in. in length. The experiments encompassed a Reynolds number range from 20,000 to 370,000, pressure range from 300 to 1500 psia, inlet superheat from 5 to 160 deg F, and film temperature differences from 30 to 550 deg F.
