摘要
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 developed. 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 goon agreement with the experimental measurements.
