Coarse Particle Motion Characteristics in a Double-Stage Slurry Pump Considering Leakage Flow

Figure 11

Distribution of particles in the cross section of the impeller at 1.2 s at Q = Q_d with or without leakage (the black circle marks the accumulation region in the first stage): (a) leakage, first stage; (b) no leakage, first stage; (c) leakage, second stage; (d) no leakage, second stage.
