Summary

CONSIDERATION IS GIVEN TO ARRAYS OF CYLINDRICAL PIN FINS, WITH AIR ENTERING THE ARRAY AT THE PLANE OF THE FIN TIPS, TURNING AS IT PASSES THROUGH THE ARRAY, AND EXITING THE ARRAY IN CROSSFLOW. PER-FIN HEAT TRANSFER COEFFICIENTS AND OVERALL PRESSURE DROPS WERE DETERMINED EXPERIMENTALLY. A COMPUTATIONAL MODEL WAS FORMULATED, WITH ACCOUNT BEING TAKEN OF THE FACT THAT THE SAME RATE OF AIRFLOW DOES NOT WASH OVER ALL OF THE FINS IN THE ARRAY. THE MODEL WAS EMPLOYED AS A BASIS FOR COMPARING THE HEAT TRANSFER RATES FOR VARIOUS ARRAYS OPERATING AT EQUAL PUMPING POWER. THE FOCI OF THE WORK WERE TO INVESTIGATE THE EFFECTS OF VARIOUS FLUID INLET AND EXIT GEOMETRIES AND ALSO TO UTILIZE MORE CLOSELY SPACED FINS THAN IN THE PAST.
