Abstract
In this investigation, the effect of column diameter and flow rate on the mixing characteristics of fluidized beds were studied.
Tests were made on columns of 4, 6, 8 and 10 inches in diameter using water to fluidize glass beads of 0.0185 inches in diameter. The tests were run both at minimum and three times minimum fluidization. Step, impulse, and sinusoidal forcing signals were fed to the columns, using a sodium chloride solution as a tracer with the inlet and outlet concentrations being monitored continuously by a conductivity recorder.
The result of this study showed increased fluid dispersion with increasing column diameter. However, the best results were found using the step and impulse forcing signals. Only partial success was obtained using sinusoidal inputs.
