โฆ Synopsis
The laminar burning velocity of propane-air mixtures has been measured in the pressure range 0.4 to 40 atm and temperature range 298 to 750 K for equivalence ratios from 0.8 to 1.5. The measurements were made in a constant-: volume spherical combustion bomb which could be heated to 500 K. A thermodynamic analysis was used to calculate the laminar burning velocity from a pressure time history of the combustion process. The measured values were correlated using both power law and exponential expressions.
