[P02-19] Computational Method for Free-Surface Flows between Multiple Absorbent Particles
Keywords:absorbent particle, seepage flow, finite volume method
A computational method was proposed for the free-surface flows between multiple absorbent particles on the basis of the finite volume method with the collocated grid system. The proposed method was applied to the dam-break flows in the porous media, which consists of multiple absorbent particles, to confirm its applicability. As a result, it is demonstrated that the free-surface flow patterns are largely affected by the swelling particles and that the flows between particles are possibly blocked by the swelling particles in case that the water absorption speed is sufficiently high.
