Figure 13: Interfacial area concentration (IAC) development in axial direction for superficial gas velocity is 1.21 m/s, superficial liquid velocity is 4.67 m/s, and average volume fraction is 0.205. At vertical position, (a) L/D = 25; (b) L/D = 148; (c) L/D = 253, at horizontal position, (d) L/D = 25; (e) L/D = 148; (f) L/D = 253.
