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.
