This project involves an experimental study of the moisture transport           process that occurs during the drying of granular porous media.  In             principle, the mechanisms are quite simple--diffusion of water vapor in         the gas phase owing to gradients in the partial pressure and convection         in the liquid phase owing to capillary forces.  Recent visual studies           have clearly indicated that the influence of local heterogeneities is           dominated by two parameters:  the Bond number (ratio of surface tension         effects to gravitiational effects) and the variance of the particle             size distribution.  To explore a wide range of Bond numbers, the                investigator will use packed beds of glass spheres ranging from 100 to          1000  microns.  The influence of the variance of the particle size              distribution will be explored using mixtures of spherical particles and         mixtures of crushed glass particles.
