Applying Imaging Technique to Investigate Effects of Solute Concentrations and Gas Injection Rates on Gas Bubble Generation

Figure 6

The effects of sodium dodecyl sulphate (SDS) surfactant concentration on bubble size distribution (BSD) for five different gas injection rates: (a) 5 ml/min, (b) 10 ml/min, (c) 20 ml/min, (d) 30 ml/min, and (e) 40 ml/min. (f) The linear mean bubble size of BSD varied with SDS surfactant concentrations. (g) The standard deviation (STD) of BSD varied with surfactant concentrations.
