A four - poles magnet was installed to apply the cusp - shaped magnetic field to air in the cubic enclosure. A simple model equation was derived for magnetizing force and numerically computed for the system. Without a magnetic field, the conduction was stable, but under the magnetizing force a strong downward flow occurred from the center of the top heated plate and the average Nusselt number attained Nu = 1.17 at Ra = 105 and J = 0.5, which is equivalent to a temperature difference of 4 [°C] between the top and bottom walls under a maximum magnetic induction of 0.9 [T] inside a cube of (0.064) (3) [m3] heated from above. The flow visualization experiment with hot incense smoke proved the downward flow from the top hot plate. Opini Anda Klik untuk menuliskan opini Anda tentang koleksi ini! Kembali
