Opis:: The results of neutron radiography studies on convective drying of kaolin cylinders are presented. The sample shrinkage and loss of water during drying was easily observed on registered neutron radiograms. The saturation of the sample with water was estimated in terms of the neutron effective macroscopic cross-section. The results are comparable to those of gravimetric measurements and are discussed within the framework of simple theories of drying. The effect of the scattered neutrons is discussed in terms of the results of the MC simulations.

Opis:: The convectional drying of rectangular block of wet mortar was investigated with thermal neutron radiography technique supplemented with traditional mass and temperature measurements. The time evolution of the drying process was recorded for rectangular sample of aged mortar before and after painting its lateral sides. The receding boundary of the central core wet region was observed in the advanced stage of the process. The size, shape and water content of that region were determined for both cases of non-painted and painted sample. It was shown that in the advanced drying process the receding drying front exists irrespectively of the drying pattern observed at the early period of drying.

Opis:: The spontaneous wetting and drying of flat porous samples of linen, cotton and synthetic textiles were studied using dynamic neutron radiography (DNR). The progress of the wetting process of the media was delineated from the obtained neutron dynamical radiography images. The results of the investigation reveal a non-classical behaviour of kinetics of wicking of these materials. The character of the wetting kinetics is discussed in terms of the fractal character of the tortuosity of fabric capillaries.
