چکیده مقاله:
Experimental study is performed to analyze heat transfer characteristics as well as thermal performance of a new type of perforated fin withcross openings. For measurements, an array of these fins over a flat surface is made from aluminum and two cross circular holes are drilled in each fin. The tests are conducted in a wind tunnel which produces uniform air motion upstream of the test case. Temperature measurements are carried out by means of calibrated thermocouples system and surface temperature measurement is determined by a thermograph imager. Results of thermal structure and heat transfer are plotted for Reynolds numbers 2×104- 4.6×104 based on the fin length.
