Two-dimensional isothermal diagram for the lateral profile of an atmosphere pressure, fuel rich, premixed, conical LPG/air flame was measured by laser tech- nique.
The local rotational temperature of OH radical for a small zone was detected by the saturated laser induced fluorescence spectroscopy of A ~2∑~+, v′=0←→X ~2Π, v″=0 transition.
The temperature distribution for the flame was measured through moving the position of the burner. The method exhibits the advantages of highly spatial resolution, unturblence, and no need of calibration.
