Reactive miscible viscous fingering occurs when a reactive and miscible less-viscous liquid displaces a more-viscous liquid in a Hele-Shaw cell. In the present study, we have succeeded to experimentally show reactive miscible viscous fingering in a Hele-Shaw cell involving changes of displaced liquid viscosity due to variations in chemical species concentrations by chemical reaction by using dependence of viscosity of polymer solution on pH. When the displaced liquid viscosity is increased by the reaction, fractal dimension of miscible viscous fingering with the reaction is larger than that without the reaction. In contrast, when the displaced liquid viscosity is decreased by the reaction, fractal dimension of miscible viscous fingering with the reaction is smaller than that without the reaction.
