Numerical simulation has been performed regarding miscible viscous fingering involving viscosity change induced by chemical reaction. Here, the solution including reactant A displaces the solution including reactant B. When the reactants A and B are in contact, A+B→C chemical reaction takes place and the product C is produced. The viscosity depends on the concentrations of B and C. Here, we focus on the conditions in which the diffusion coefficients of all species are the same and the initial reactant concentrations are equal. To enlighten effects of the viscosity of the product, we consider the condition of infinite Damkohler number D_a. Numerical results has a good agreement with the experimental results previously obtained by the authors.
