搅拌反应器是一种在化工、医药、能源和废水处理等领域应用比较广泛的设备。其中混合时间是表征搅拌反应器内物料混合状况的一个重要参数。本文从实验测量方法和数值模拟两个方面综述了近50年来对混合时间的研究,并展望了未来混合时间测量方法和数值计算的发展方向。
Stirred tanks are popularly used in chemical,pharmaceutical and energy industries and water treatment. Mixing time is an important parameter characterizing mixing status in stirred tanks. The experimental and simulation study on mixing time in stirred tanks in last five decades are reviewed in this paper. The future development of measurement and simulation methods of mixing time is discussed.
