Pressure Effect on Turbulent Flame Velocity

The container-with-agitator method has been applied to lean H2 + air mixtures with the fuel excess coefficient 0 = 0.26 (10% H2) at room temperature and 0.1, 0.26 and 0.5 MPa pressure. The flame velocity was measured by flame front boundary planimetry. 

The results obtained are presented in Fig. 3.10. No pressure effect on the turbulent flame velocity St was observed. The experimental points obtained, at 5 times initial pressure, are chaotically distributed in the area between the two dashed lines.
