Silica Aerogel Granule Size Distribution

F. 6.6 Weighted two-term Gaussian fitted function to represent the distribution of silica aerogel granules in terms of size d (cm)... 

Table 7.1 shows the classification, sample distribution, and their physical properties for each granule size. Figure 7.4 shows how the silica aerogel granules are prepared for the experiment. First, the acoustics absorption of an appropriate thin porous ply is evaluated. Then, silica aerogel granules of various sizes are filled in the impedance mbe to the depths of 10 and 15 mm covered with a layer of porous ply held...
