In this study, the influence of turbulence intensity on flame local structural and local propagation characteristics was studied. In order to achieve this, 50% H2/50% CO with equivalence ratio of 0.8 were conducted under different turbulence intensities ranging from 0 to 1.31 m/s at atmospheric pressure and temperature. The distribution of the flame local radius and flame local propagation speed and...
Taking the laminar spherical flames propagate within homogenous hydrogen-air mixture as the studied object, the effects of initial conditions (including equivalence ratio, initial pressure, and initial temperature) on propagation characteristics are systematically investigated. During propagation, global stretch rate monotonously declines towards convergence, it first rises then declines with the...
To provide more insight into the laminar burning velocity reduction of diluted syngas premixed flames, the laminar burning velocities of diluted syngas premixed (H2/CO/N2/air and H2/CO/CO2/air) laminar spherical flames were systematically and thoroughly investigated experimentally via Schlieren technology. In the present investigation, the volume fraction of H2 was varied from 30% to 70%, the volume...
