Effect of stratification on the mixing and reaction yield in a T-shaped micro-mixer

Experiments, i.e. micro-PIV and flow visualization, and direct numerical simulations, are used jointly to investigate how stratification affects mixing and chemical reaction in a T-shaped microreactor fed with two miscible liquids exhibiting a small density difference. The work analyzes the dependence of the degree of mixing on the Reynolds number and correlates the reaction yield with the Damk\"ohler number to help to devise strategies for the practical operation of microreactors with fluids of practical interest.
