Minimum spouting velocity of flat-base spouted fluid bed
Particuology, 2018 Abstract Experiments were performed on spout characteristics of a cylindrical spout-fluidized bed (I.D. = 10 cm) with different static heights and two materials (Al 2 O 3 and high density polyethylene). Results of minimum spouting velocity obtained in this study were compared with reported correlations for both spouted and spout-fluidized beds ...
