An electroresistivity sensor probe is developed and used to measure gas fraction and bubble frequency in turbulent air/water plume formed during upward injection of gas. The measured gas fraction and bubble frequency profiles at different axial positions in the plume are found to exhibit good similarity. It is found that the axial gas fraction decreases and plume radius increases with increase in axial distance. From the values of axial gas fraction and plume half radius, turbulent viscosity of liquid in bubble plume is determined and is found to be several times higher than the molecular viscosity.
