Performance of heated pin fin arrangement in a rectangular cavity-An experimental approach

For the last few decades there has been very remarkable growth in electronics and computing technologies and it is still continuing unceasingly. The performance of various engineering devices is limited by thermal management problems. The present investigation deals with heat transfer augmentation through pin fins in gamma of an air-filled rectangular cavity as function of corresponding pertinent factors- fin height, fin spacing as well as Rayleigh number and suggests a direction of future advancements. The experiments are carried out for wide domains of numerous persuading parameters- fin height (12.5 mm ≤ L ≤ 37.5 mm), fin spacing (25 mm ≤ S ≤ 100 mm) and Rayleigh number (360000 ≤ Ra ≤ 680000). Fin spacing is determined as most critical parameter affecting system performance
