Abstract
The effect of column diameter on the frequency response of water fluidized beds was investigated.
Studies were made on four columns ranging from four to ten inches in diameter. Water was used to fluidize the beds which consisted of spherical glass beads .0185 inches in diameter. A trace solution of sodium chloride was sinusoidally introduced into the beds. Inlet and outlet concentrations were continuously measured by an electrical conductivity recorder. Separate frequency response tests were conducted on the inlet calmning section in an attempt to obtain the frequency response of this region alone. Results of the tests were expressed as Bode plots.
As the bed diameter was increased, the system became more backmixed in nature. In an attempt to quantify this data, theoretical frequency response curves were calculated based on the mixing cell model. However, over the range of frequencies tested, poor correlation was obtained between this theoretical model and the empirical data.
