Particles Concentration Measurement of Fluidized Bed in Wavy Flow by Impedance Method

Abstract

Particles concentration in a fluidized bed with water pulsation for Lithium collection system in seawater has been measured using impedance method. As a result, the void fraction is increased in the lower layer and that is decreased in the upper layer as the frequency increases. Moreover, the void fraction in the lower layer has a reasonable agreement with the Richardson- Zaki equation. The amplitudes of vibration in the lower and upper layers increase as the frequency increases. However, it is not changed among the frequencies in the middle layer.
