Heat transfer rates and friction variations are experimentally presented for a horizontal pipe with the insertion of an airfoil made from aluminum alloy 6010-T4 of average roughness 0.4 μ m. The test foil is tested at two temperature conditions, cold and hot. Fully developed laminar airflow is maintained in the test duct section, which is connected to a sub-sonic wind tunnel. The airflow characteristics is determined at different flow speed and foil tilt positions. The heat transfer rate, drag force coefficient, and Reynolds number results show a strong dependence on the test foil angle positions. It’s found that the larger foil tilt angle position, the larger is the drag coefficient and the higher is the heat transfer rate. Infra red thermograph and computer simulation using Fluent code 6.3.26 are used to support the experimental work.
