Enhancement of thermal conductivity and kinematic viscosity in magnetically controllable maghemite (γ-Fe2O3) nanofluids
The objective of this study is to investigate the thermal conductivity and kinematic viscosity enhancement of maghemite nanofluids at various particle volume fractions (0.1%, 0.2%, 0.3%, 0.4%, 0.5% and 0.6%) under the influence of an external magnetic field in different orientations (parallel and pe...
