Abstract:

Flow is examined in the regime of ignition of laminar boundary layer on an impermeable flat plate when a uniform supersonic flow of a stoichiometric misture of gaseous hydrocarbon fuel and air approaches the plate at a zero angle of attack. It is assumed that there is no external pressure gradient, the temperature of the plate is constant, and the concentrations of the chemical components on the external boundary of the boundary layer are equal to their initial values in the approaching flow. As a result of numerical integration of the nonself-similar equations of the boundary layer by the method of grids, the dependence of the plate length necessary for the formation of a flame front upon the basic kinetic coefficients and values of the parameters of the approaching flow is found.
