Abstract

An experimental investigation has been performed to determine the constant surface temperature heat transfer behavior on the upper surface of a rectangular model with a chord length of 20.3 cm (8 in.) and an aspect ratio of 6/1. Data were obtained for angles of attack from 0 to 50 deg and freestream velocities of 9.1, 15.2, and 21.3 m/s (30, 50 and 70 ft/s). Separation existed on a portion of the upper surface for angles between 0 and 20 deg with the flow being turbulent after reattachment. Above 30 deg the flow was always laminar with the stagnation point on the upper surface. The heat transfer results in the laminar case were strongly influenced by freestream disturbances.
