Description
Summary:A novel method of studying mass transfer processes in porous media has been considered. The method allows one to carry out operation monitoring of the diffusivity in thin articles without destruction of them and in the absence of preliminary calibration of the equipment used to measure the diffusant concentration. The method has provided an increase in the accuracy of measuring sought characteristics of the mass-transfer due to the possibility of selecting measured parameters that enter the calculation equation at sections of the static characteristic of a converter with high sensitivity and noise immunity.
