Fig. 8.

Predicted effect of polydisperse particle size distributions on filtration performance when the suspension contains large spherical particles having a fixed diameter d_p,pb = 1.8 mm and smaller spherical particles having an adjustable diameter d_p,f . (Top) Visualization of the final cake structure when the diameter ratio $\frac{d_{p,pb}}{d_{p,f}}=3$, 6 or 12 (a–c) where the larger particles are red spheres and the smaller particles are blue spheres. (Bottom) Corresponding model predictions of (d) specific cake resistance (e) filtrate mass flow rate and (f) pressure drop spatial profile where 0 is the bottom of the cake.
