AbstractA single-beam gamma-ray densitorneter capable of precise vertical and horizontal scanning bas been developed for the study of hydrodynarnic phenornena in gas/liquid and gas/liquid/solid multi-phase flow colurnns. Studies were made on thick-walled reactors at elevated ternperatures and pressures for hydrogen/organic liquid systems. Under these con:Utions, rnethods that rely on the insertion of sensors cannot be employed easily. Time dependent garnrna-ray attenuation caused by gas bubbles passing through the fluid was rneasured at different positions and under various conditions in two vertical continuous-flow colurnns. In addition to time averaged attenuation recorded by a single-channel scaler for measurement of mean local voidages, probability density distributions (PDD) were measured in order to investigate the homogeneity of bubble distributions. A statistical rnodel was developed to deconvolute the PDD function and to correlate thern with the instantaneous voidage. Analyses show that this technique is a powerful tool for the determination of void fraction and flow regime.
