Abstracts: The human civilization is due to development of energy conversion devices and it is an important element of progress of society. The Industrial Revolution began when James Watt invented the steam engine in 1765; today we live in the “nuclear age,”, being thermal energy the main primary source of energy. Oil, coal, and gas are the three most important fuels for powering the modern world. Clearly fossil fuel reserves are finite - it's only a matter of when they run out - not if. Globally - every year we currently consume the equivalent of over 11 billion tonnes of oil in fossil fuels. Crude oil reserves are vanishing at the rate of 4 billion tonnes a year1 – if we carry on at this rate without any increase for our growing population or aspirations, our known oil deposits will be gone by 2052. We’ll still have gas left, and coal too. But if we increase gas production to fill the energy gap left by oil, then those reserves will only give us an additional eight years, taking us to 2060. Heat transfer devices are very essential to transfer the heat generated by the combustion of this fossil fuels almost in every industry. Therefore the effective heat transfers from the surface of heat exchanger are very crucial. This project aims to study the enhancement of heat transfer mechanism by extended surfaces. An experimental setup is to be developed to study enhancement in heat transfer characteristics by extended surface. Parallely, using different available correlation will be studied by extensive literature review to suit for the proposed experiment study. Later stage, numerical analysis based on advanced CFD software ANSYS will be under taken for different arrangement. Finally the experimental and numerical data will be validated with published correlation.
