Characteristics of Enhanced Heat Transfer of Nanofluid in Microchannels Under Electric and Magnetic Co‐Excitation

Asia-Pacific Journal of Chemical Engineering, Volume 20, Issue 6, November/December 2025.
ABSTRACT Due to its small size, microchannel heat exchangers are widely used in fine engineering fields such as electronic equipment. In this paper, the boiling heat transfer characteristics of refrigerants and nanofluids in microchannels are studied by applying electric fields, magnetic fields, and electromagnetic synergistic fields.
