The importance of coil in shell heat exchanger is recognized in many industrial applications ranging from petrochemical, pharmaceuticals steam and water sampling system (SWAS). The presented study is focused on the thermal design, CFD analysis and experimentation of single stream, single phase, and double helix helical coil heat exchanger. The thermal design is prepared by using the basic equations and the correlations. It focuses mainly on parameter like heat duty, pressure drop, heat transfer area, Overall heat transfer coefficient, length of coil, number of turns, Reynolds number, Prandtl’s number, etc. CFD analysis has been carried out for a coil in shell single stream, single phase, and double helix helical coil heat exchanger. The analysis is done using Star CCM +12.06. Experiment is carried out on heat exchanger, consisting of helical coil with a length of 3 m and tube diameter 1” (25.4mm). The experiment is performed under controlled environmental condition. The hot water flows at sample side and cold water at the cold side. The temperature for the water inlet is fixed at 29.5 deg C whereas the hot water inlet is almost kept at 55 deg C.The key points for the analysis are the outlet temperatures, heat duty and pressure drops for cold side. During experimentation, in first case both the mass flow rates of hot and cold side are kept contant.Then the outlet temperature of hot as well as cold side, heat duty and pressure drop are monitored. In second case of experimentation, the mass flow rate of cold side is varied up to 500 lph.Then the effect on heat duty and pressure drop is studied. The result obtained from the experiment is stored in data acquisition system which gives the outputs such as heat duty, flow rates, drop in pressure and temperature for the heat exchanger
