Investigation of the singularities of distribution of cesium atoms in the boundary layer of the flow of combustion products

The distribution of the temperature and concentration of cesium in the cross section of the boundary layer of combustion products formed on the surface of a flat metal plate is measured. A model of chemical kinetics is selected, and numerical simulation of the behavior of cesium in the boundary layer of combustion products is performed. A comparison of the results of numerical calculation with the results of measurements on a cooled and uncooled plate demonstrates that the suggested model of chemical kinetics describes the measurement results with good accuracy. The effect of different reactions, as well as of the processes of condensation and thermodiffusion, on the distribution of free atoms of cesium in the boundary layer is analyzed.
