目的
采用光滑粒子流体动力学（SPH）方法对固体颗粒的溶解过程进行了数值研究。
设计/方法/方式
为了实现溶解，对流扩散质量传输方程求解计算粒子。随后，当这些颗粒的浓度低于一定阈值时，它们从溶质中分解。
结果
结果表明，溶解的实施是在良好的协议与文献中的可用数据。固体颗粒的溶解进行了研究，为一个广泛的雷诺数和施密特数。将二维（2D）结果与三维（3D）情况进行比较，以确定2D结果在3D溶解现象建模中的准确性。
独创性/价值
本数值模型能够解决制药，生物化学，食品加工和洗涤剂工业中的相关问题。
Purpose
The purpose of this paper is to numerically study the dissolution of solid particles using the smoothed particle hydrodynamics (SPH) method.
Design/methodology/approach
To implement dissolution, an advection–diffusion mass transport equation is solved over computational particles. Subsequently, these particles disintegrate from the solute when their concentration falls below a certain threshold.
Findings
It is shown that the implementation of dissolution is in good agreement with available data in the literature. The dissolution of solid particles is studied for a wide range of Reynolds and Schmidt numbers. Two-dimensional (2D) results are compared with three-dimensional (3D) cases to identify where 2D results are accurate for modelling 3D dissolution phenomena.
Originality/value
The present numerical model is capable of addressing related problems in pharmaceutical, biochemical, food processing and detergent industries.
