Perte de pression et vitesse minimum de fluidisation dans un lit de particules 2D

Abstract

In order to determine the pressure drop equation and the minimum fluidization velocity of a 2D bed of monodispersed particles, an experimental setup has been devoloped. The first results show clearly that the well-known equations for 3D bed are not reliable for this configuration. In particular, the minimum fluidization velocity is underestimated. A new pressure drop law is proposed which allows the determination of the minimum fluidization velocity, and is in good agreement with the experimental measurements.
