Heat transfers from pin-fin arrays experiencing forced convection

Steady-state heat-transfers from pin-fin arrays have been investigated experimentally for staggered and in-line arrangements of the pin fins, which were orthogonal to the mean airflow. For the applied conditions, the optimal spacings of the fins in the span-wise and streamwise directions have been determined. The dependences of the Musselt number upon the Reynolds number and pin-fin pitch (in both directions) have been deduced. © 2000 Elsevier Science Ltd. All rights reserved.
