Enhancing the heat transfer rate is an important factor in a heat exchanger. One of the most widely accepted way to enhance heat transfer rate is by using twisted tapes inside tubes. Many researches are done on twisted tapes by using full length, half length and reduced width twisted tapes of various twist ratios. It is found that lesser the twist ratio more is the heat transfer rate, but pressure drop also increases and hence reduced width tapes are mostly used in turbulent flows. From the various research studies it can be concluded that most of the studies are done for twist ratio greater than two and also half length tapes are preferred over full length tapes. No study is done on the effect of reduced width tapes instead of half length tapes in laminar flow which may reduce the pressure developed. This work focusses on performance enhancement of the heat exchanger experimental setup using reduced width twisted tapes over full as well as half length twisted tapes inside tubes having twist ratio equal to 1 for laminar flow.
