Void fraction measurement in foams using needle shaped conductivity probes


Void fraction measurement in foams using needle shaped conductivity probes

Kern, T.

Needle Shaped Conductivity Probes have been applied to measure the properties of aqueous alcohol foams. Simultaneous usage of gamma densitometry and video imaging should allow a calibration and prove the values of the probe. The results show that the conductivity probes are able to measure in the foam zone as well as in the bubbly flow whereas the geometry of the foam causes some problems to detect reliably the foam bubbles.
