Liquid-solid Fluidization: Effect of Rheological Behaviour of the Fluid on the Structure Development and the Expansion Reduction of Spherical Particle Bed

Popis výsledku v původním jazyce

In process design calculation, the fluidization of monodispersed beds of solid particles with liquids is usually considered to be uniform. However, extensive investigations of expansion of beds of solid particles fluidized with different kinds of non-Newtonian liquids performed in our laboratory showed that the expansion course had depended in a great measure on rheological behaviour of the fluid. In our contribution, an experimental study was carried out to identify inhomogeneities and structure of fluidized beds of solid-liquid systems in which the suspending liquid exhibited both Newtonian and non-Newtonian rheological behaviour. The fluidization of the solid particle bed was carried out in the transparent Perspex test column of rectangular cross-section. The beds of particles were composed of nearly uniform glass spheres with diameter from 1.4 to 4 mm. As test liquids were used aqueous solutions of Maltose, polyalkylene glycol Emkarox, hydroxyethyl-cellulose Natrosol and polyacryla
