Heat recovery is the capture of energy contained in the fluids otherwise that would be lost from the facility. The heat exchangers are the important in the engineering system with wide variety of applications including power plants, nuclear reactors, refrigeration, air conditioning system, heat recovery systems, chemical processing and food industries. Helical tube heat exchanger (HTHE) is a device which is used for heat recovery system because of fluid dynamics inside the pipes of a helical coil heat exchanger offers certain advantages over the straight tubes. The experimental set up of the heat exchangers consist of a shell through which cold water flows and the hot water flows through the tube which configured in helical tube in the set up. The centrifugal force developed due to the helical curvature of tubes resolve in the secondary flow development, which may be the key factor enhancements of heat transfer. The present project work is to investigate the performance of the counter flow heat exchanger experimentally, analytically by using CREO & solid works for enhancement heat transfer coefficients of fluid in helical tube for pitch and curvature ratio and compare the experimental and analytical values of helical coil heat transfer coefficient for counter flow arrangement.
