Abstract
A fiber optic probe for measuring the local void fraction in a two-phase
(air–water) flow has been developed. The liquid-gas and gas-liquid
interfaces are detected by the normal reflections of IR laser light at the tip
of a multimode fiber. The probe and its associated electronic circuitry were
calibrated by using the averaged void fraction measured by a quick closing valve
system. The void profiles obtained by this method were compared with those
obtained by a conductivity local probe. The proposed optical system shows a
better sensitivity at high void fractions.
