On the role of nanofluids in thermal-hydraulic performance of heat exchangers - a review

摘要: Heat exchangers are key components in many of the devices seen our everyday life. They employed applications such as land vehicles, power plants, marine gas turbines, oil refineries, air-conditioning, and domestic water heating. Their operating mechanism depends on providing a flow thermal energy between two or more mediums different temperatures. The thermo-economics considerations have set need for developing this equipment further, which is very challenging when taking into account complexity operational conditions expansion limitation technology. For reasons, work provides systematic review state-of-the-art heat exchanger technology progress towards using nanofluids enhancing their thermal-hydraulic performance. Firstly, general theory presented. Then, an in-depth focus types exchangers, plate-frame plate-fin Moreover, introduction to developments, thermophysical properties, influence performance also discussed. Thus, primary purpose not only describe previously published literature, but emphasize important role how category advanced fluids can significantly increase efficiency possible future applications.
