The paper proposes a mathematical model consisting of three levels. The first level of the model is based on the equations of quantum mechanics. The level is auxiliary and is used to calculate energy parameters and potential coefficients. The second level of the model is based on the molecular dynamics apparatus and considers the processes of atoms and molecules condensation into nanostructures. At the third level of the model, the already formed nanoclusters are scrutinized and their further aggregation is implemented. We describe the movement of clusters through equations of particle mesodynamics. The formulated mathematical model in the work is applied to a set of two specific issues. The first task considers the process of aggregation of nanostructures used to power plants from the gaseous medium through pores in the stems and leaves. And the second task is to investigate the process of condensation of nanoclusters during the operation of a fire extinguishing gas generator.
