Static and dynamic combined effects on the thermal conductivity of water based Ironoxide Nanofluids: experiments and theories

Reasoning of particular mechanism of anomalous thermal transport behaviors is not identified yet for the nanofluids. In this research, the thermal conductivity of maghemite (MH) nanoparticles dispersed deionized water (DW) nanofluids (MH/DW) has been evaluated for the first time using the modifi...
