With the use of decomposition into dynamic modes, reduced models of hydrodynamic mixing have been constructed and rather exact space–time pictures of impurity distribution for various periodic regimes of mixing have been obtained with substantial reduction of computational expenditures. It is shown that after processing the results of solution of the problem on mixing in a rectangular cavern with mobile bottom and lid by the DMD method, the gain in the information storage amounts to more than 80%. The proposed approach can also be applied for processing experimental data.
