摘要：

Axial and radial temperature profiles of the gaseous slab in between two symmetric counterflow premixed flames of methane are measured. For widely separated lean and rich flames there exists a temperature dip which is accounted for on the basis of radiative heat loss. For lean flames, the dependence of the temperature dip on the flame separation distances is determined. The calculated total radiant loss from the transparent gas volume results in average temperature drops which closely agree with the measured values. The influence of the thermocouple coating thickness on the measured temperature is reported. Application of the present experimental method to the evaluation of effective emissivities of combustion products of different fuels is discussed.
