Abstract
The effects of pressure on the outwardly propagating turbulent flames were studied for propane-air mixtures at the equivalence ratios from 0.8 to 1.3 and the initial pressure from 0.10 to 0.50MPa. The turbulence intensity of the mixture was set to 0.80 and 1.59m/s. The ratio of turbulent burning velocity to unstretched laminar burning velocity increased with the increase in the initial mixture pressure at all the equivalence ratios. It seemed to increase as the Markstein number decreased. Laminar flames with the small Markstein number were unstable. Turbulent flame seemed to be affected by the flame instabilities.
