Gas-based nanofluids (nanoaerosols)

Gas-based nanofluids or nanoaerosols are defined as any aerosol created with nanometer-scale particulates, typically 1-100 nm. Similar to their liquid counterparts, gas-based nanofluids have the potential to increase the thermal conductivity as well as the heat capacity of the base gas and therefore enhance the heat transfer performance of the gas. Initial investigation of gas-based nanofluids came from their potential application in gas-cooled nuclear power plants, particularly for advanced gas-reactor cooling such as the gas-cooled fast reactor or the high-temperature gascooled reactor. Gas nanofluids are also of great interest in the fusion reactor diverter cooling system. Improved heat transfer performance of gas coolants would have a significant impact on the performance and safety of gas-cooled nuclear power reactors, as well as, many other technologies.
