Keywords:superabsorbent polymer particles, fluid-solid interaction, particle-scale swelling process, SAP particle experiment, 3D multiphase computation method

This paper presents the experimental results in which multiple superabsorbent polymer (SAP) particles were
dropped into water to measure the height of the particle layer deposited on the bottom. In addition, the
swelling process was numerically predicted with a three-dimensional computation method which deals with
fluid-solid and solid-solid interactions to confirm its applicability and discuss the subjects to be improved.
