Abstract: Heat transfer enhancement techniques can be divided into two categories passive and active. In passive heat transfer enhancement an object which does not use external energy, such as groove inside the tube, has the duty of increasing the heat transfer rate. Forced convection heat transfer is the most frequently employed mode of the heat transfer in heat exchangers or in various chemical process plants. Corrugated pipes are used in various engineering applications such heat exchangers and oil transport. In most cases these pipes consist of periodically distributed grooves at the duct inner wall. In the present study there are three shapes of grooves semi-circular, rectangular and trapezoidal with varying depth introduced internally to generally used pipes in heat exchangers to investigate the heat transfer enhancement within the Reynolds number range of 5000 to 12000 with heat flux at the outer walls of pipes. CFD analysis is carried out through Ansys Fluent using K epsilon turbulence model. The Results found to be are that the trapezoidal performs with effectiveness (Nu/Nuo) of 21 to 29% more over rectangular and semi-circular grooved pipe. And also thermal hydraulic performance of 5-8% over circular grooved pipe and 30-50% over rectangular grooved pipe. Trapezoidal grooved pipe also shows least pressure losses over other grooved pipes at all depths.
