ABSTRACT
A mesh-coupled axial blade distributor was tested for fluidization of particles in a swirling
fluidized bed. The bed velocity was estimated experimentally using a high-speed imaging
device and MATLAB supported particle image velocimetry (PIV). The bed velocity was also
predicted statistically with a response surface analysis method. During statistical analysis,
the confidence interval of bed velocity remained between 0.49485 and 0.49998. The bed
velocity was measured about 0.49741m/s and 0.538m/s through experimental and statistical
methods, respectively. The experimental and statistical analysis revealed similar bed weights
and superficial velocities with a slight difference of 6.4◦ in blade angles.
