| Outline of Final Research Achievements |
In this work, numerical simulation models are developed to predict the mixing of powder and liquid in wet granulation processes. The developed models are used to investigate the impact of the microscopic particle structures on the powder-liquid mixing speed. It was succeeded to develop a DNS model to simulate the liquid penetration due to capillary action as well as a particle contact dispersion model. Linear relationship was found between the cosine of the apparent contact angle of the powder mixture with different contact angles and the volume ratio of the mixture. In addition, it was implied that the partial wetting of individual particle surface can significantly influence the contact liquid dispersion speed.
