Segregation of equal-sized particles of different densities in a vertically vibrated fluidized bed.
In this collaborative work with Profs. Tsuji (Osaka University) and Acosta-Iborra (Carlos III University, Madrid) we studied the influence of vibration and fluidization on density-induced segregation of particles in a pseudo-2D vibrated fluidized bed.
By introducing vertical vibration to a bed that is fluidized close to minimum fluidization the rate of segregation and the final segregation index is enhanced. However, for vibration strengths greater than a critical value of ~ 3.5, the degree of segregation decreases with increasing fluidization.
