Modeling Pulse Properties near the Bubble-to-Pulse Transition in Randomly Packed Beds

Figure 2

(a) Sample bifurcation diagram very near the “transition” predicted from linear stability (G_trans = 0.054 kg/m²·s). The air/water system under microgravity is with d_p = 2 mm and L = 15 kg/m²·s. (b) Sample bifurcation diagram farther away from the “transition” predicted from linear stability (G_trans = 0.054 kg/m²·s). The air/water system under microgravity is with d_p = 2 mm and L = 15 kg/m²·s.
