Abstract

Film theory has often been used to calculate the dissolution rates of solid particles. However, it is only good for the case of low solubility solids due to the assumption of pseudo‐steady state. In this study, we propose a more refined model to facilitate the characterization of the dissolution of spherical solid particles in a stagnant fluid. The results indicate that the film theory will overestimate the dissolution time for the case of high solubility, while for low solubility particles, the film theory is quite accurate in predicting the dissolution time.
