9361543 Kelkar Funded under and SBIR Phase 1 grant, research is to be conducted on mixing in agitated vessels stirred by a rotating impeller. While such mixers have been in use for a very long time, predicting mixing performance in a new design is still highly empirical and uncertain. This research is to develop a computer model of the process based on a novel method for allowing the method to couple the rotating flow near the impeller with the more irregular non-rotating flow elsewhere in the mixer. Software is to be developed for dealing with this situation as a tool for optimization and scale-up. Beyond permitting mixing equipment manufacturers to create optimized designs with such a predictive tool, the code will have other possible applications in all fluid systems where only parts of the flow are rotating. ***

9361543 Kelkar在SBIR第一期资助下，研究将在旋转叶轮搅拌的搅拌容器中进行混合。虽然这种混合器已经使用了很长时间，但在新设计中预测混合性能仍然是高度经验和不确定的。本研究是基于一种新的方法来开发一个过程的计算机模型，该方法允许该方法将叶轮附近的旋转流动与混合器中其他地方更不规则的非旋转流动耦合起来。将开发软件来处理这种情况，作为优化和扩大规模的工具。除了允许混合设备制造商使用这种预测工具进行优化设计外，该规范还可以应用于所有流体系统中，其中只有部分流体是旋转的。＊＊＊
