In recent studies, we have shown that the evaporation rate studies of liquid drops placed on solid surfaces can provide much useful information (ref. 2). In this report we will describe the evaporation of liquids from porous media. The porous media consisted of different types, e.g. small glass spheres, solid powders as kieselguhr and catalysts. 

Kato (K3) measured so-called critical gas velocities corresponding to the complete suspension of solids, and presents a graphical correlation of the results for glass spheres (diameters from 0.074 to 0.295 mm), magnetite particles (particle size from 0.038 to 0.175 mm), and sand particles (particle size 0.147 to 0.295 mm). 

Fig. 15. 2-D slice sections through 3-D MR images of water distribution within an initially water-saturated packing of 500-pin glass spheres. Voxel resolution is 94 pm x 94 pm x 94 pm. Data are shown before drying commenced and at three time intervals during the drying process. Only the water within the inter-particle space of the bead packing was imaged (white pixels). No signal was obtained from the solid and gas phases present.

Kato, et al (5 ) measured solid concentration profiles, solid dispersion coefficients and terminal settling velocities for glass spheres in water, using 6.6, 12.2 and 21.k cm bubble columns. They developed a dimensionless, empirical correlation for the solid dispersion coefficients which agreed with their observed values to within 20%. 

Imafuku et al.46 measured the gas holdup in a batch (i.e., no liquid flow) three-phase fluidized-bed column. They found that the presence of solids caused significant coalescence of bubbles. They correlated the gas holdup with the slip velocity between the gas and liquid. They found that the gas holdup does not depend upon the type of gas distributor or the shape of the bottom of the column when solid particles are completely suspended. Kato et al.53 found that the gas holdup in an air-water-glass sphere system was somewhat less than that of the air-water system and that the larger solid particles showed a somewhat smaller... 

Figure VB-2 Comparison of QEj (EL) (solid dots) with QE ,(PL), both measured under the same conditions for devices with different luminescent polymer thicknesses. Open squares PL efficiency as obtained when the incident light intensity was corrected by directly measuring the sum of unabsorbed and reflected light for each individual device outside of the integrating sphere. Solid x s PL efficiency as obtained when the incident light intensity was corrected by measuring the transmittance and reflectance of EL polymer films of different thickness on the glass substrate, following the procedure of Greenham et al. (Taken from ref 158)...
