Micromixing complicated by a chemical reaction in a statistically homo
geneous turbulent flow is studied. Integral micromixing models for an
arbitrary number of independent variables are proposed. The case where
the micromixing of components is accomplished with different rates is
considered. Equations for conditional moments are obtained. Discrete
analogs of the micromixing models, which radically simplify the proced
ure of numerical calculations, are built. The interaction between the
micromixing process and the chemical reaction is analyzed.
