DYNAMICS OF RADIAL SOAKING OF A MATERIAL WITH A DISPERSED MEDIUM

Processes of capillary absorption of a liquid by a material have been investigated. A design has been proposed for a device to assess the physical and chemical condition of the material by the dynamics of its soaking. Taking into account the device′s design and the specifi c features of the liquid′s travel in the capillary system of the investigated material, differential equations describing the dynamics of its soaking have been obtained. Results have been presented and analyzed of experimental investigations of a paper′s circular soaking with different dispersed media. Based on the obtained data, model dependences have been constructed, using which optimization of the developed device′s design has been implemented.
