Planar Laser Induced Fluorescence of OH for Thermometry in a Flow Field Based on Two Temperature Point Calibration Method

In view of the uncertainty in calibration process two-color plane laser-induced fluorescence (PLIF) temperature measurement, a new method is proposed, which influence yield considered. The was carried out at high and low region, respectively. Then, bias thermometry results origin from quenching restrained. This validated jet flame with range 1300–1800 K. Here, Coherent Anti-Stokes Raman scattering (CARS), single-point calibrated PLIF, two-point PLIF are all acquired maximum standard errors 13 K, 36 37 deviation between average (CARS) 120 K 10 when one-point methods used. Therefore, preferred combustion field, especially large strong coefficient.
