Experimental analysis of enclosure aspect ratio influence on thermo-magnetic convection heat transfer

Experimental analysis of strong magnetic field influence on paramagnetic fluid's convection in rectangular enclosures with aspect ratios (AR=height/width) 0.5 and 2.0 was conducted. For this purpose, enclosure filled with paramagnetic fluid was placed inside superconducting magnet in Rayleigh-Bénard configuration and temperature measurements of the fluid were performed, with and without magnetic field induction. On the basis of performed research, analysis of heat transfer and character of the flow was conducted. Obtained results allowed characterization of fluid behavior and demonstrated that the aspect ratio has an immense influence on quantitative heat transfer in the system. (paper)
