Determination of gas-liquid bubble column instantaneous interfacial area and void fraction by a real-time neutron radiography method

In this work, the axial profiles of a gas-liquid bubble column instantanous interfacial area and void fraction are determined by a RTNR method. The void fraction was also determined independently from liquid level and an ultrasonic transmission method for comparisons. In the sieve plate apparatus, there is no net flow of liquid, and the gas phase is dispersed homogeneously by the plate into bubbles of approximately equal size across a 5.4 cm ID …
