Neutron Radiography Applications in Studies of Drying of Capillary-Porous Systems

Abstract: The application of modern digital neutron radiography in the study of the drying process in porous media is demonstrated with two simple examples of cylindrical and rectangular samples made of different materials. The statistical method of image analysis is presented and the standard deviation of grey scale values (referred to brightness) is shown to be a useful measure of receding drying front emergence. The motion of the drying front was analyzed and found neither linear nor proportional to the square root o… Show more

“…Our previous analysis [9,11] conrmed that the presence of the second maximum in the plot of the standard deviation was due to the development of the limited inner wet region and the motion of the drying front towards centre. The observed shift of the second maximum towards later times with increasing salt concentration was certainly due to the later development and slower motion of the drying front in samples with larger salt content.…”

“…These results show that the drying process was slower for solutions containing larger salt amounts. The physical processes occurring inside drying cylinders and their eects on the neutron radiographs have been described previously within a two-cylinders model of the sample [9,11]. Within this model the brightness radial proles and the standard deviation of brightness have been explained.…”

“…NR has been shown to be an excellent tool for determination of the spatial distribution of the water inside granular capillary-porous media [26,28], and so it can be applied in the field of drying. The main merit of this imaging technique is the high contrast between the dry and wet regions of the sample body in the images [3,18].…”
