Experimental studies on two phase inverse fluidization using non-Newtonian fluid.

Inverse fluidization is a type of fluidization process, in which a downward flow of a continuous liquid phase over a solid particle, whose density is lower than the density of the liquid. The parameters of hydrodynamics such as pressure drop, bed expansion, and minimum fluidization velocities were studied. In the present investigation, sodium Chloride (NaCl) and Sodium Carboxyl Methyl cellulose (SCMC) considered as a continuous liquid phase with low density particles of polyethylene (LDPE) and activated carbon from date seeds as a solid phase. Typical Pressure drop–superficial velocity plots and Bed expansion ratio - superficial velocity plots for different density variations using (5%, 10% and 15% NaCl solutions) and different viscosity variations using (0.1%, 0.3%, and 0.5% SCMC solutions) is shown and the bed expansion behavior is evaluated.
