The improvement in performance of a double pipe heat exchanger fitted with twisted tape as a turbulence promoter with twist ratios of 15.649, 8.54, 5.882, 4.95, and 4.149 was experimentally studied. A maximum percentage gain of 44.7% in energy transfer rate was obtained for the twisted tape of twist ratio 4.149. For all twist ratios, the gain decreases with the Reynolds number and becomes constant for Reynolds numbers greater than 3,000. The smaller the twist ratio is, the larger the gain in energy for a specific Reynolds number.
