Abstract
The hydrodynamic behavior of an iron and iron-sand beds is investigated in the presence of an externally applied uniform magnetic field collinear with gas flow. In addition heat-transfer measurements from a horizontal electrically heated probe are conducted. The gas velocity is varied over a wide range to bring about different regimes for different magnetic-field intensity values in the range 0–9641 A m −1. The minimum bubbling velocity and heat-transfer coefficient values are discussed and correlated. It is found that bed voidage and segregation of admixture components play a very important role in establishing the hydrodynamic and heat-transfer characteristics of the magnetofluidized beds.
