English Abstract

-The research in this thesis presents the effect of inclined fluidized bed at different inclination angles(90o, 75o , 60o , and 45o) with and without promoter on bed dynamics relating to minimum fluidization velocity, bed pressure drop, bed expansion and fluctuation with column inclination have been experimentally and computationally investigated.

The study included manufacturing of three different types of promoters used in the investigation (rod type with four numbers of varying rod configuration and blockage with open area 95.27%, 92.24%, 89.22%, 84.68%, disk type with seven types of varying disk thicknesses and diameters with open area 82.98%, 61.24%, 27%, and ring-type with three types of varying ring thicknesses and open area 72.2%, 48.8%), Other system variables included bed materials of different sizes and densities and initial static bed heights.

In the computation, an Artificial Neural Network using Particle Swarm Optimization and back propagation with and without promoter has been used.

Four different Artificial Neural Network models; one for unpromoted bed and three beds promoted with rod, disk, and ring type promoter have been used for the prediction of bed expansion ratio and bed fluctuation ratio by using the package MATLAB version (6.5).

Developed correlations of Artificial Neural Network models are based on experimental data for the prediction of bed expansion ratio.
