| Summary: | The heat transfer process occurs all the time around us, from simple household appliances to equipment used in large industries. Energy efficiency in large-scale use in industry is necessary because it is related to company profits. One way to save energy use in heat exchangers is to change the thermal properties of the cooling fluid. The addition of particles of the nanometer size (nanofluids) in the working fluid will improve the performance of the heat exchanger, and the main goal is the highest efficiency. In addition, there is another method to increase the heat transfer rate, namely, by vibrating the cooling fluid. This chapter will discuss combining nanofluids and ultrasonic vibrations in heat transfer processes in heat exchangers. The application of these two methods simultaneously gives rise to several advantages to the heat transfer system, will promote higher heat transfer, and at the same time function as cleaning of scale/deposits that often appear on the surface of the heat exchanger. |
