Experimental Investigation of Heat Transfer to a Threaded Cylinder in Crossflow.

Abstract

An experimental investigation of heat transfer to cylinders in crossflow was conducted at the Hydrogen Heat Transfer Facility of the Air Force Aero Propulsion Laboratory. The heat transfer at the stagnation line of a cylinder with circumferential threads, 0.010 inches deep and 0.015 inches wide, was compared with the heat transfer to a smooth cylinder. The investigation covered the Reynolds Number ranges of 38,000 to 118,000. A hollow cylinder(1.25 inches OD) was instrumented with foil heat flux sensors and fixed behind a hydrogen combustor. Gas temperatures did not exceed 1060 R.
