EXPERIMENTAL STUDY ON TEMPERATURE DEPENDENCE OF CAPILLARY FLOW IN POROUS MEDIA BY ACOUSTIC EMISSION METHOD

For the first time, the acoustic emission (AE) method applicability to study the processes ongoing in the microporous medium under capillary pore filling with liquid is investigated. In particular, the temperature contribution to the dynamics of the porous materials impregnation is studied. The expe...

description For the first time, the acoustic emission (AE) method applicability to study the processes ongoing in the microporous medium under capillary pore filling with liquid is investigated. In particular, the temperature contribution to the dynamics of the porous materials impregnation is studied. The experimental results have shown that the most informative AE parameters reflecting the capillary liquid rise dynamics are the signal sum and the oscillation sum. The curve shape of the signal sum dependence on the AE amount follows the curve shape of the dynamic pattern of changing in the liquid elevation through the capillaries of the ceramic sample constructed from the experimental data. At the beginning of the capillary rise, the AE activity is significantly higher at higher temperatures. With increase of the liquid capillary rise, the process intensity decreases. The experimental data indicate that the AE parameters reflect the impregnation dynamics and kinetics under any change in the impregnation conditions, and they can be used for the remote process control.
