Investigation of distribution of lithium atoms in the boundary layer of the flow of combustion products

The results are given of measurements of the profiles of temperature and concentration of lithium in the cross section of the boundary layer formed under conditions of flow of combustion products of propaneair flame past the surface of a flat metal plate. A model of chemically nonequilibrium laminar boundary layer is used to perform numerical simulation of various components of the combustion products. A comparison of the measured profiles of lithium concentration and profiles of hydrogen atoms obtained from the experimental data with the predicted results on a cooled and uncooled plate demonstrates that the suggested model of chemical kinetics describes the measurement results with good accuracy.
