- Bubble Size Analysis | Practical Surfactants Science - Steven Abbott
Take a picture of the bubbles, using the black white contrast obtained by contact with a prism, and automatically identify each true bubble in the image, count the number of pixels in that bubble, then calculate how the bubbles are distributed over various sizes
- Measurement of Bubble Size Distribution by Passive Acoustic Method
In this paper, the authors proposed a passive acoustic method for determining the size of air bubbles in water The advantage of this method is that, unlike active methods, it is invasive, i e does not affect the gas-liquid stream under study
- 11 - Bubble size measurements and foam test methods
Several non-intrusive analytical techniques have been used to provide information on bubble size distributions, gas fraction, texture and general characteristics of foams

11 2 Bubble size measurements le fi – fi shapes and the extent of anisotropy Image analysis and optical probe techniques have been used to measure the average bubble size and change
- A simple technique for the automation of bubble size measurements
The bubble sizes as well as the size distributions play an important role in determining the final properties of the fluid bubble mixture and therefore need to be known with sufficient precision For this purpose, numerous techniques have been developed in the past, including liquid scattering [5], acoustic methods, or laser scanning techniques

METHODS OF BUBBLE MEASUREMENTS As the size distribution is the most important characteristics of the oceanic bubble population necessary to be measured, much effort was directed toward designing a reliable, simple, and wide-range bubble spectrometer
- Laboratory air bubble generation of various size distributions
In this study we investigate the production capability of eight inexpensive bubble generators using optical imaging techniques Specific emphasis is directed towards determining bubble size and distribution for a given device, flow conditions, and type of water used (fresh vs salt)
- Bubble size distributions in gasliquidsolid systems and their influence . . .
Thus, this paper is focused on measurements of bubble size distributions by changing surfactant dosage, solid percentage, air velocity and particle size as well as establishing the
