Abstract
Macro- and micro-behaviors of soluble granular media during dissolution process is investigated by numerical analysis. Soluble media are represented by assemblies of non-soluble particles and soluble particles with the different soluble particles contents. Dissolutions of particles are implemented by reducing sizes of soluble particles. The numerical simulations results exhibit that the vertical displacements increase to certain times and become constant while the porosities still increase until no soluble particles are present. However, the porosities and vertical displacements increase with the increase of soluble particles content. The microscopic views show that the fabrics of media change during dissolution process until the certain times, the higher soluble particles contents, and the larger change in fabric.
