反应喷雾干燥过程,如喷雾聚合,在过程强化方面非常有趣。然而,对这些过程的研究主要是基于实验的。在这一贡献中,我们提出了喷雾聚合的单液滴模型,该模型一维地解析了喷雾液滴内部的反应扩散系统。该模型能够模拟工艺参数和材料性质对聚合结果的影响,并提供了链长分布的数值和质量平均值等重要数值。
Reactive spray drying processes such as spray polymerisation are very interesting with respect to process intensification. However, research on these processes is mainly based on experiments. In this contribution, we present a single droplet model of spray polymerisation, which resolves the reaction diffusion system one-dimensionally inside the droplets of a spray. The model is able to simulate the influence of process parameters and material properties on the polymerisation result and provides important values such as number and mass average of the chain length distribution.
