CO behavior in laminar boundary layer of combustion product flow

Results are reported from the experimental investigation and numerical simu lation of the laminar boundary layer formed on the flat plate in flowing co mbustion products of propane in air. During the experiments such parameters as the temperature of the plate surface and the composition of the oncomin g flow (due to a change of the fuel to air equivalence ratio phi) have been varied. In addition, when performing numerical simulations, the catalytic properties of the surface have been changed. The comparison of the measured profiles of velocity, temperature, OH and CO concentrations with the resul ts of the calculation based on the chemically reacting boundary layer model has revealed that the model adequately described both distributions of par ameters in the boundary layer and their dependence on the boundary conditio ns and parameters of the free stream flow.
