要約(英語): The purpose of this paper is to propose a new simulation model of the hydrogen generation reaction by activated aluminum particles and water. Specifically, it was assumed that the particles were composed of blocks and that the reaction proceeded along the blocks. It is considered that there are numerous nano-cracks form on the surface of the activated aluminum particles and the cracks progress from the surface of the particle to the inside. Therefore, hydrogen generation is thought to be closely related to the progress. First, the crack growth with the hydrogen generation reaction was measured using acoustic emission method. Second, the crack growth was calculated using the proposed model. The initial crack position and crack amount on the proposed model were determined based on the laser microscope image. The crack growth coefficients were determined based on the measured deformation-energy during hydrogen generation. The simulation results were consistent with the change in the integrated value of the normalized deformation-energy. Therefore, it was confirmed that the proposed model is effective to describe the crack growth with the reaction of the hydrogen generation.
