The need to increase the thermal performance of heat transfer equipment (for instance, heat exchangers), thereby effecting energy, material, and cost savings, as well as a consequential mitigation of environmental degradation, has led to the development and use of many heat transfer enhancement techniques. These methods are referred to as augmentation or intensification techniques. This project deals with the analysis of heat transfer augmentation for fluid flowing through pipes using CFD. Using CFD codes for modeling the heat and fluid flow is an efficient tool for predicting equipment performance. CFD offers a convenient means to study the detailed flows and heat exchange processes, which take place inside the tube. Friction factor and Nusselt number for water flowing through the specified pipe were obtained first for the smooth pipe and then for the pipe with a single/double triangular tape insert in the Reynolds number range and Prandtl number. Calculated values (obtained from empirical equations available in literature) were compared with CFD values. Comparisons were also made between the smooth tube results and the single/double triangular tape results to establish the heat transfer augmentation due to the use of the insert. Simulations were carried out using commercial CFD software ANSYS.
