Abstract
This paper describes an investigation of the local mixing and chemical reaction in microchannel by using chemiluminescence to estimate the local chemical reaction rate. The chemical reaction in the micro-fluidic device is strongly affected by its mixing performance. In this study, the chemiluminescence is applied to visualize the local chemical reaction in the microchannel. The chemiluminescence intensity profile clearly shows the mixing layer at an interface between two liquids. The reaction rate constant was estimated from chemiluminescence decay measured by completely mixed area in the microchannel. The local chemical reaction profile can be estimated quantitatively from the chemiluminescence intensity profile.
