INTENSIFICATION OF A PRESSURE WAVE IN A COMBUSTION ZONE (OB USILENII VOLNY DAVLENIYA V ZONE CORENIYA),
Abstract
The purpose of the work is to establish a relation between the parameters of a compression wave passing through the combustion zone and the kinetic characteristics of the chemical reaction. For deriving the analog of the wave equation it is proposed to use the dependence between the density, pressure, and fraction of burned gas instead of the isentropic dependence of density on pressure. For solution of the derived equation the report utilizes the condition of smallness of the pressure variation. However, the produced simplification is insufficiently substantiated; it is not clear why one of the nonlinear terms of the equation is left together with the linear terms. The result of the investigation produced by approximation methods indicates that the compression wave is intensified with its passage through the combustion zone. The effect of various parameters of the reacting mixture on the magnitude of intensification is found in qualitative agreement with experimental data. (Author)
