Effect of the water spray stress on swirling fluidized bed height
This study was designed to investigate the effect of spray stress and pressure drop on the height of a swirling fluidized bed of plastic beads. The motivation for conducting this work was primarily an interest in elaborating the fluidized particles response to the water sprayed from top of the bed....
