A mixing process in a staggered toothed -indented shaped channel was investigated. It was studied in two steps : (1) numerical simulations for different sizes of the boundary - contour were performed by using a CFD code ; (2) these results were used for simulation - data modeling for prediction of mixing performances across the whole field of changing geometric and the aerodynamic stream parameters. Support vector machine (SVM) technique, known as a new type of self learning machine, was selected to carry out this stage. The suitability of this application method was demonstrated in comparison with a neural network (NN) method. The established modeling system was then applied to some further studies of the prototype mixer, including observations of the mixing performance in three special cases and performing optimizations of the mixing processes for two conflicting objectives and hereby obtaining the Pareto optimum sets.
