Abstract

In many process industries the high performance heat transfer systems are considered very important for various applications. The augmentation techniques aim to increase the heat transfer which will affect on the performance of heat exchangers. The process industry is continuously working to incorporate enhancements in heat transfer. There are two types of augmentations techniques used in practice, the active and the passive technique. The active technique requires power from outside devices like fan, blower etc. while passive technique does not requires any power from outside. The performance of heat exchangers in terms of hydraulic and thermal, can be improved with surface enhancement. To study the thermo hydraulic performance when helical wire coil is used as insert, an experiment is carried out under an uniform heat flux condition. During the experimentation, air is used as working fluid. The analysis is carried out for a turbulent flow when it is fully developed. The values of Reynolds number (Re) range, based on a test tube inside diameter, from 6,000 to 12,000. The data are obtained from the experimentation and compared with the slandered smooth tube data available in the literature.
