Influence of Roughness on Heat Transfer and Transition: ART Program Data Report

Abstract

In order to assess the direct influence of surface roughness upon heat transfer and its indirect effect through the shift in transition location, a series of wind tunnel tests were carried out. A fixed body shape (with one exception) with varying roughness was tested at a series of tunnel conditions and the heat transfer measured by the thin wall calorimeter method. The wind tunnel conditions and the heat transfer distribution around the models are presented in tabular form.
