Minimum fluidization velocity of binary mixture of particles with large size ratio

The minimum fluidization velocities for systems of binary particles of greatly different sizes and densities have been studied experimentally. Particles of different shapes such as wood chips, rubber sheets, glass beads, iron beads, soya beans and small beans were used as coarse particles and nearly...

Description
Summary:The minimum fluidization velocities for systems of binary particles of greatly different sizes and densities have been studied experimentally. Particles of different shapes such as wood chips, rubber sheets, glass beads, iron beads, soya beans and small beans were used as coarse particles and nearly spherical fine particles of sands and glass beads were used as a fluidized medium. The correlation for the estimation of the true minimum fluidization velocity at which both coarse and fine particles are completely fluidized was obtained by the modification of the equation of Wen and Yu. This equation provides a good estimate of the minimum fluidization velocity for binary systems.
