CFD simulations are performed to study the micro-mixing in a T-mixer with square bends by using the Villermaux-Dushman reaction. The calculated segregation indices are compared with previously published data and it is shown that whilst the trend is capture the simulation overpredict the extent of miccromixing. This paper provides guidance on the computational requirements needed to obtain accurate results in such laminar flows and shows the complex species fields that develop within the reactor.
