A new mathematical model of humidified hydrogen-oxygen combustion is built to describe combustion blending and cooling water evaporation process. One-dimensional simulation of different hydrogen-oxygen inlet and cooling water conditions are carried out to get the inlet parameters of influencing on humidified combustion by Eu-ler-Lagrange method. The conclusion can provide a reference for analyzing humidified hydrogen-oxygen combustion process and designing combustion chamber.
