Simulations of 3D fluid flows and mixing have been performed inside in-line mixers (a tee mixer and an axisymmetric mixer), for a single phase flow, in turbulent conditions. The 3D velocity fields are used to calculate the mixing phenomena inside of this mixers and the driving forces of mixing are brought to the fore. The mean concentration fields are presented. Emphasis is put on the great importance of the post processing, because the raw results are impossible to examine in the case of a 3Dcalculation.
