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

Figure 6

Shape change of single bubble rising process under pulsation condition.

(a) Re = 5, Bo = 10, = 0.05m/s, = 0.7, τ = 0.2s/Re = 5, and Bo = 10 (static condition: red-dashed line)

(b) Re = 10, Bo = 10, = 0.05m/s, = 0.7, and τ = 0.2s
