A wide variety of industrial processes involve the transfer of heat energy. Throughout any industrial facility, heat must be added, removed, or transferred from one process stream to another a phenomenon becoming a major task for industrial necessity. These processes provide a source for energy recovery and fluid heating or cooling process. Enhancement of heating or cooling in an industrial process may create a saving in energy, reduction of process time, raising thermal rating and lengthen the working life of equipment. Some processes are even affected qualitatively by the action of enhanced heat transfer. The development of high performance thermal systems for heat transfer enhancement has become lately popular. This research work helps to create awareness on how effective nanofluids are in heat transfer.
