Résumé

Experiments have been performed to determine the heat transfer coefficients for forced convection airflow over a cylindrical obstacle that is inclined and yawed relative to the oncoming flow. The experiments encompassed a wide range of angles of attack and angles of yaw, and extended over a Reynolds number ranging from about 1000 to 7000. It was found that owing to three-dimensional flow effects, the heat transfer coefficients were remarkably insensitive to both the angle of attack and the angle of yaw. This enabled all the results to be correlated by a simple equation, with an accuracy of plus or minus 4%. Flow visualizations were explored to broaden their fundamental understanding of the heat transfer outside the tube.
