MODELING THE SYNTHESIS OF BARIUM TITANATE MICRON PARTICLES IN AXISYMMETRIC DIRECT-FLOW AND THREE-ZONE REACTORS

A study is made of heat- and mass-transfer regime in a porous medium consisting of gas and solid reactants and products of synthesis of micron particles during the motion of a combustion front in cylindrical channels with account of thermal and mass dispersions. A model of a three-zone reactor is proposed, and a comparative analysis is made of the infl uence of dispersion on the process of operation of fl ow and three-zone reactors. Modeling results for different geometric parameters of the synthesis reactors are compared. A comparison is made of the results of calculating the synthesis of barium titanate and calculating for the model without thermal dispersion. Advantages of the three-zone reactor are noted
