Abstract

The power consumption characteristics of an agitating impeller in a uniform suspension, in which coarse particles with the same density as that of the liquid were suspended, were investigated. Power consumption was measured under various conditions : particle size distribution of suspended particles ; volume fraction of particles in suspension ; and impeller speed.<BR>It was found that power number increased with increasing mean diameter of particles and volume fraction of particles in suspension, while power number decreased with increasing packing fraction of particles. In the range of Reynolds number N_Re, 6.43 × 10⁴ ≤ N_Re ≤ 1.07 × 10⁵, the power number did not change with N_Re. The empirical formula, which shows the relationship between power number and suspending condition of particles, was obtained.
