Water Steam Effect on Laminar Flame Velocity

Let us consider the effect of noncombustible additives, such as water steam, carbon dioxide or nitrogen on the laminar flame velocity along with combustion of binary fuel mixtures (H2 + CO and H2 + CH4). 

9 Carbon Dioxide Effect on Laminar Flame Velocity 

2 Laminar and Cellular Combustion of Hydrogenous Gaseous Mixtures 

The solid curve - water steam diluent, the dashed curve — CO2 diluent 

The temperature and pressure effect is illustrated in Figs. 2.23 and 2.24. The curves represent the dependencies of laminar flame velocity on the temperature with a variable pressure parameter. It is seen that the velocity grows with the temperature increase at a fixed pressure, but it falls with increasing pressure at a fixed temperature value.
