FLOW FIELD, DRAG, AND HEAT TRANSFER OF A HEATED CYLINDER IN A SUBSONIC CROSSFLOW OF AIR

Abstract

In this study flow field, drag, and heat transfer characteristics of a mica cylinder heated by nichrome ribbon were investigated. Measurements were performed in a wind tunnel at velocities of 40 to 160 fps, and at heat input rates of zero to 188 Btu/hr-sq. in. Average cylinder surface temperatures ranged from 250 F to 1100 F above atmospheric temperature. Cylinder surface pressure distributions indicated the flow was subcritical and separation was laminar. Pressure drag was satisfactorily calculated from cylinder pressure distributions. Total and dynamic pressure distributions in the wake showed an increased depression with increased rate of heat input. Heat transfer data correlated satisfactorily with Douglas and Churchill.
