Experiments have been carried out recently to investigate the turbulent heat transfer and friction characteristics of a turbulent airflow inside a rib-roughened rectangular duct. It has been widely accepted that artificial roughening on a surface enhances the rate of heat transfer in a heat exchanger. Experiments utilizing 6.35mm square-sectioned X-shaped ribs of various angles of attack with respect to the airflow were performed in order to search for an optimum angle of attack. Preliminary results showed that the aluminum ribs at 64° angle of attack would produce the best heat transfer performance for a given friction factor. This trend is also shown to be true for all friction factors investigated and agrees well with early numerical simulation work. A scaling law for the heating curve close to the optimum angle was obtained and it was of the form Nu∿Re^<0.49> for θ=60°.
