HELICAL coil tube are used to enhanced the heat transfer coefficient and also accommodate a large heat exchange surface in a given volume. Higher performance and compactness are primary requirements of heat and mass transfer devices hence researchers are trying towards heat enhancement techniques with reduction in size of heat exchanger. Recently, developments of helical coil type heat exchangers are being used because the helical coil configuration has the advantages of more heat transfer area and better flow. This is due to the curvature effect of the helical coil. Nano particles have been a topic of interest to many researchers. The wide range applications and advantages of these materials give them a superior edge over conventional materials. Nano particles have higher heat transfer rates which makes them an optimum choice where a higher heat transfer rate is required for smooth functioning. Nano particles such as TiO2 and SiO2 have been studied. From several studies of previous authors it has been observed that curvature ratio is most predominant factor in helically coiled tube that affect heat transfer characteristics, hence main objective behind present study is to investigate experimentally the effect different curvature ratio of helical tubes with working fluid as water with nano particles. From experimental analysis it is found that compactness i.e. surface area density increases with different curvature ratio. It is also found that heat transfer coefficient increases with increase in curvature ratio but at the expense of pressure drop in helical tube.
