The unsteady wall heat transfer during laminar flame quenching was studied in a constant volume combustion chamber for premixed propane-air mixtures. The wall heat flux was determined for different initial pressures and different ignition locations. The dependence of the maximum wall heat flux on the pressure and the unburned gas temperature prior to quenching was obtained. A relationship between the measured maximum wall heat flux and the head-on quenching distance was also obtained.A quasilinear method was used to solve the unsteady, one-dimensional conservation equations during laminar flame quenching. The results of the calculations for the unsteady wall heat flux are in good agreement with the experimental data.
