The aforementioned experiments are also useful for inferring the cause of the higher amounts of 1 observed at the end of the reaction at larger scales. Bourne  has identified three mixing stages for single-phase fluids: (a) distributive, or macromixing, in which large fluid eddies exchange positions and mass, but with compositional uniformity occurring only at a scale greater than the eddy size; (b) dispersive, or mesomixing, in which larger eddies are reduced in size due to turbulent shear and finer-grained mixture forms, but with the mixture remaining highly segregated at the molecular scale; (c) diffusive, or micromixing, in which molecular diffusion occurs over short distances between finely dispersed structures to give a mixture that is randomized on the molecular scale. Good micromixing is thus a prerequisite to avoiding compositional inhomogeneities on the molecular scale (i.e., high local concentrations) that can impact selectivity of chemical reactions. The macromixing time typically increases with increasing scale.
For example, when scaling up at constant power per unit volume in geometrically similar vessels, the macromixing time varies as the 2/3 power of the vessel diameter. At constant power per unit volume, however, the micromixing time is not impacted significantly. Thus, given that the stages occur mostly in series, one should expect a longer time to achieve uniformity at the molecular scale with increasing scale (i.e. macromixing becomes the limiting mixing process).I don't know what I thought about the time it took for material to achieve homogeneity in a 1 liter flask (in this case.) But now I'm aware of the eddies!
