摘要

本研究的第一部分提出了一个准稳态模型,用于准确预测多分散球形(扁球形、扁球形和球形)颗粒体系以扩散为主的详细溶解过程。本文广泛研究了典型多分散球形颗粒体系的溶解特性。通过研究详细的溶解过程,如单个颗粒的尺寸减小率、体积浓度的增加以及多分散体系的溶解时间,对颗粒尺寸和形状分布的影响进行了研究。确定了一些控制溶解过程的重要因素,包括初始颗粒浓度、最小和最大颗粒尺寸以及最小和最大泰勒形状参数。

Quasi-steady-state modelling and characterization of diffusion-controlled dissolution from polydisperse spheroidal particles, II: characterization

A quasi-steady-state model for accurately predicting the detailed diffusion-dominated dissolution process of polydisperse spheroidal (prolate, oblate and spherical) particle systems was presented in Part I of this study. In the present paper, the dissolution characteristics of typical polydisperse spheroidal particle systems have been extensively investigated. The effects of the distributions of particle size and shape have been studied by examining the detailed dissolution processes, such as the size reduction rates of individual particles, the increase in bulk concentration and the dissolution time of the polydisperse systems. Some important factors controlling the dissolution process, including initial particle concentration, smallest and largest particle sizes, and the smallest and largest Taylor shape parameters, have been identified.
