Comparison of mixing index for binary and ternary mixtures of irregular particles in a gas-solid fluidized bed

Ternary mixtures of equi‐density particles have been fluidized in a gas–solid fluidized bed to study the mixing characteristics. A correlation for the mixing index has been developed for these mixtures. The mixing index for the ternary mixtures has also been calculated by the already available metho...

Description
Summary:Ternary mixtures of equi‐density particles have been fluidized in a gas–solid fluidized bed to study the mixing characteristics. A correlation for the mixing index has been developed for these mixtures. The mixing index for the ternary mixtures has also been calculated by the already available method. Finally a comparison has been made for the values of the mixing index calculated by both the methods against the experimental ones. The values of the mixing index for the ternary mixtures thus obtained have also been compared with those of the binary mixtures thereby indicating its application for real life multi‐component mixing over a wide range of parameters. Des mélanges ternaires de particules d'équi‐densité ont été fluidisés sur un lit fluidisé gaz‐solide pour étudier les caractéristiques de mélange. Une corrélation pour l'indice de mélange a été développée pour ces mélanges. L'indice de mélange pour les mélanges ternaires a également été calculé par la méthode déjà disponible. Finalement, une comparaison a été faite pour les valeurs de l'indice de mélange calculées par les deux méthodes, par rapport aux valeurs expérimentales. Les valeurs de l'indice de mélange pour les mélanges ternaires ainsi obtenues ont aussi été comparées à celles des mélanges binaires, indiquant ainsi l'application possible pour des mélanges de composants multiples de la vie réelle et pour une grande diversité de paramètres.
