Glass slug A particle of glass sometimes taking the form of a glass bead, which is imperfection in glass fibers. 

The need for analytical (flow-pattern) characterization in advance of the experiment is less than for the dispersive mixers forming slug and annular flow patterns, because the dispersion typically is formed in an attached tube. This tube is commonly made of glass and mostly of larger inner diameter. Hence visual inspection by the operator is routinely possible. 

Procedures. The light reflectance instrument was turned on 30 min prior to initiating reflectance observations. The sensitivity switch was set in the low position. The combination visible light emitter-reflectance detector was positioned vertically the active end of the detector faced upward. The sample cup was a glass cylindrical cuvette with optically flat bottom. A constant mass of 165 g (brass slug) was placed on top... 

Many speoles feed exelusively on Inseots and other Invertebrate pests, Ineluding slugs and snails. This legless glass lizard Is a major slug predator. 

The surfactant adsorbs on water-wet glass beads. Experiments reported in Ref. 27 show that about 0.5 HCPV of surfactant solution is required to satisfy the adsorption capacity of the bead pack. Hence, when a slug size of 0.2 HCPV of carbon dioxide and an equal slug of surfactant solution are injected together, the surfactant is all adsorbed when about 40% of the volume of the bead pack has been contacted. This is apparently sufficient to obtain the benefits of... 

Figure 45 illustrates the plot of (f/c f mf)/cb versus (C/g Umi) according to Eq. (5-8) for fluidized beds. In the figure, Eq. (5-4) is also shown for slugging beds. The mean gas holdup for the FCC-catalyst bed is taken from Fig. 36. The plot for the FCC bed shows clearly that the bed is fluidized smoothly, without slugging. The plot also shows data for a bed of fluidized glass beads of mean diameter of 287 m. (Data are taken from W13 cf. Fig. 14). The bed behavior is seen to approach that of the slugging bed as(f/c f/mf) increases beyond 20cm/sec. Also, the averagers is approximately 0.8 for Uq < 20 cm/sec, showing the possibility of bulk recirculation of the emulsion.
