COLLISIONAL ENERGY TRANSFER IN OH(A2Σ+): INVESTIGATIONS FOR QUANTITATIVE LIF COMBUSTION DIAGNOSTICS
SINOPSIS
A multi-level rate equation model for the simulation of energy transfer in OH (A2Σ+) following laser excitation has been developed. The required rates for rotational energy transfer (RET) and electronic quenching are modelled on the basis of measured RET coefficients (as represented by an Energy Corrected Sudden (ECS) scaling law) and lifetimes. The rate equation model has then been used to study the influence of RET and quenching on the accuracy of linear LIF temperature measurements. The results of this study illustrate the sensitivity of two-line LIF thermometry to the ratio of total RET versus quenching and to the rotational level dependencies of RET, quenching and radiative lifetime.
