Void-fraction liquid metals

Fiber-Bed Scrubbers Fibrous-bed structures are sometimes used as gas-liquid contactors, with cocnrrent flow of the gas and hqnid streams. In such contactors, both scrubbing (particle deposition on droplets) and filtration (particle deposition on fibers) may take place. If only mists are to be collected, small fibers may be used, but if solid particles are present, the use of fiber beds is limited by the tendency of the beds to phig. For dnst-cohectiou service, the fiber bed must be composed of coarse fibers and have a high void fraction, so as to minimize the tendency to plug. The fiber bed may be made from metal or... 

Liquid metals represent a special case in the estimation of two phase void fractions. Because of the great differences in vapor and liquid density, very low qualities correspond to high void fractions, and for the same reason very large slip velocity ratios occur. In a recent paper. Smith et al. (S13) review previous measurements of void fractions in...
