An experimental investigation was conducted to determine the heat transfer and flow characteristics for a rectangular finned surface subject to circular impinging jets with forced crossflow. The jet array was configured to impinge on the top of the fins while the crossflow was directed through the channels formed by the fins. Tests were performed to determine the overall heat transfer under conditions of only jet impingement, only crossflow and combined jet with crossflow. Results are presented in terms of necessary pressure to drive the flow as well as in terms of the jet and channel Reynolds numbers. Nusselt number correlations indicate the ability to optimize the jet and crossflow with the fin geometry to obtain specific heat transfer conditions.
