Numerical Study of Bubble Rising and Coalescence Characteristics under Flow Pulsation Based on Particle Method

Figure 10

The change of bubble centroid rising velocity with time under the influence of each independent variable.

(a) The effect of Re on the velocity (case a-d)

(b) The effect of Bo on the velocity (case a, e, f)

(c) The effect of on the velocity (case a, , h)

(d) The effect of on the velocity (case k-o)

(e) The effect of τ on the velocity (case a, i, j)
