Summary

In comparison with single-phase heat transfer devices, equipment with two-phase heat transfer mechanisms has significantly better thermal performance. Heat pipes are heat transfer devices working based on the phase change of the operating fluid with significantly remarkable heat transfer capacity. There are different kinds of heat pipes such as oscillating heat pipes, wick heat pipes, thermosyphon, and loop heat pipes. Heat pipes have been used for a wide variety of applications such as thermal management of fuel cells, solar photovoltaic modules, cooling of electronic devices and desalination systems due to their relatively simple structure and high heat transfer capacity. Operating fluid and its thermal properties have a significant impact on the performance of heat pipes. Regarding the potential of nanofluids in the enhancement of thermal characteristics of heat pipes, these fluids have attracted attention to be employed as heat pipes’ working fluids. Magnetic nanofluids that are composed of ferromagnetic nanostructures such as nickel, cobalt and magnetite have significant potential for enhancement of thermal characteristics of heat transfer mediums. Furthermore, there are some more phenomenal features regarding their magnetic nature that can induce more improvement in the performance of heat pipes. This special issue focuses on the applications of magnetic nanofluids in various kinds of heat pipes. Both review and original articles with high quality are welcome to be submitted to this special issue. The main interests- but not limited- topics are outlined as follows:
