The performance of solar water heater can be improved to perform a certain heat transfer duty by heat transfer enhancement techniques. In general, these techniques can be divided into two groups: active and passive techniques. The active techniques require external forces, e.g. electric field, acoustic or surface vibration, etc. The passive techniques require fluid additives or special surface geometries. Curved tapes have been used as one of the passive heat transfer enhancement techniques and are the most widely used techniques in several heat transfer applications. The main categories of heat transfer augmentation involves insetting curved tapes, helically coiled tapes, spirally coiled rods, other coiled tubes and also using fins are studied and analyzed to determine the optimum technique for a solar water heater by improving the convective heat transfer between the circular pipe and water medium. Simulations were carried out using commercial CFD software ANSYS FLUENT 14.0.
