Study on reacting polymeric liquid flows by combined analysis of rheological measurement, computational fluid dynamics, and chemical molecular measurement

为了发展反应体系中的流体动力学，我们对反应液体流动进行了基础研究，重点研究了液体的特性。特别是通过流动实验、流变学测量、计算流体力学和化学分子测量相结合的分析方法，研究了反应性聚合物液体流动和带有沉淀物的反应性流动。首次发现了化学反应引起的粘度变化引起的不稳定对流和沉淀反应引起的不稳定对流，化学反应生成的凝胶对流动的影响主要取决于凝胶的流变性。

To develop fluid dynamics in reactive systems, we performed fundamental study on reacting liquid flows focusing on liquid specific property. Especially, we studied reacting polymeric liquid flows and a reacting flow with a precipitation by combined analysis of flow experiment, rheological measurement, computational fluid dynamics, and chemical molecular measurement. We have found, for the first time, unstable convection induced by viscosity change due to chemical reaction, unstable convection induced by precipitation reaction, and that influences of the gel produced by chemical reactions on flows significantly depend on the rheological property of the gel.
