In this work, experimental and numerical results on the effect of diffusion and geometrical dispersion on the mixing of two fluids when interacting at the intersection of confluent channels are presented. Channels are 4 mm diameter and intersect with an angle =30, 60, 90, 120, 150, 180◦. The experimental setup allows to accurately control the caudal and assures a constant flow at both inlets. The mixing properties are studied by injecting pure water in one inlet and colored water at the other. The effects of the inlet flow and the intersection angle on the diffusion of ink is analyzed. We observed that the mixing by convection is only important for  a= 180◦. For other angles, diffusion is the main mechanism for mixing.=30, 60, 90, 120, 150, 180◦.
