EFFECTS OF POROSITY AND PORE SIZE DISTRIBUTION ON CAPILLARY WATER TRANSFER IN POROUS MEDIA
In this study, we built a simple experimental apparatus for measuring water transfer rate.The experimental results were then used to investigate the effects of porosity and pore size distribution on capillary water transfer in porous media.Several types of cylindrical porous ceramics were used as sample porous media.In addition, we considered a method for predicting the moisture transfer coefficients on the basis of the pore size distribution.The results showed that the water transfer rate increased with the porosity.In addition, the water transfer rate for unit porous area was affected by the pore size distribution.Further, we developed a method for predicting the moisture transfer coefficients of the samples using theoretical analysis.
