The flowmeter operates across the entire gas volume fraction range, avoiding frequent recalibration.
There are several quantitative terms: gas volume fraction (GVF) is the volume of the gas flow divided by the total volume of fluid flowing.
However, the models have limitations on application to a dilute bubble suspension and clear maximum packing fraction does not exist since bubbles are deformable and the relative viscosity varies continuously with respect to the gas volume fraction when [empty set] is smaller than 0.
For high gas volume fractions, this is known as "wet gas measurement," but I'll lump it all together for this discussion.
In our previous investigation on injection foams, we have shown a relationship between linear viscoelastic properties and the gas volume fraction .
Other products include the Volumetric Flow Monitoring System, Gas Volume Fraction Monitoring System, the Gas Holdup Meter, Active SONAR meter, Gas Fraction Meter and Total Air Monitor.
In regards to the foaming of thermoplastic polyolefins (TPO), which will be discussed in this study, data in the literature has shown that these systems exhibit Regime 2 flow behavior where the viscosity is reduced with increasing gas volume fraction [29, 30].
Firstly, sound speed of low frequency, one-dimensional pressure waves in aerated mixtures provides first principles insight into the gas volume fraction of the mixture.
