Local Void Fractions and Bubble Velocity in Vertical Air-Water Two-Phase Flows Measured by Needle-Contact Capacitance Probe

Figure 19

Data processing results for typical two-phase flows.
(a) Plug flow (a long bubble)
(b) Bubbly flow ( m/s,  m/s)
(c) Slug flow ( m/s,  m/s)
(d) Churn flow ( m/s,  m/s)
