Abstract
This work experimentally and numerically investigates the effect of water addition up to a mole fraction of 0.15 on the burning rates of H2 and H2/CO mixtures from 1 atm-10 atm at a flame temperature near 1600K. Burning rates were measured using outwardly propagating spherical flames in a nearly constant pressure chamber. Results show good agreement with the newly updated hydrogen kinetic model for H2 flames, and H2/CO flames. The results show a monotonic decrease in mass burning rate with water addition at pressures above 1 atm, as well a decrease in the pressure at which the maximum burning rate occurs. Path analyses reveal the influence of water addition on the radical pool through H2O+O=2OH.
