Abstract

Water vapor is one of the major products from hydrocarbon combustion. It's important to measure its concentration. The optimal line fitting function, Voigt function, was selected based on existing theories. Suitable absorption lines were chosen with HITRAN database. Method of temperature calculation using line strength ratio of two selected H_2O transitions was analyzed, and experiment equipment was set up based on TDLAS.
