“…Figure 3 shows that our measurements at 1.5, 2, and 3 atm are in very good agreement with those of Goswami et al 6 obtained using the same heat flux method. The agreement is also satisfactory with measurements made at 2 atm by Hassan et al 21 and Rozenchan et al 24 in constant volume bombs.…”

“…Measurements using the new experimental setup have been made up to 6 atm for methane and burning velocities compared satisfactorily with the data of Goswami et al 6 New measurements have then been made in the case of n-pentane, a liquid linear alkane representative of those present in gasoline, up to 4.2 atm. Experiments for both fuels have also been made at atmospheric pressure at temperatures up to 398 K. Comparisons between experimental results for n-pentane and simulations using a detailed kinetic model of literature are shown.…”

A new adiabatic burner allowing the measurement of burning velocities at high pressure with the heat flux method has been developed. Experimental measurements of laminar burning velocities of methane and n-pentane were performed for pressures up to 6 atm at 298 K and at atmospheric pressure for temperatures from 298 to 398 K. Equivalence ratios varied from 0.6 to 1.9. The results for methane flames are in good agreement with the only results of literature obtained above atmospheric pressure using the heat flux method; those for n-pentane are to our knowledge the first application of this method to a flame of a liquid fuel above atmospheric pressure. Based on these measurements, empirical correlations of the variation of the measured laminar flame velocities with pressure and temperature have been proposed for methane and n-pentane. In the case of methane, these correlations lead to a satisfactory prediction of literature measurements made using constant volume bombs.

“…While attempting to extend the heat flux method towards high pressure, our intention is to design a system that stabilizes a flat adiabatic flame and not compromise the stretchless nature even at elevated pressure. Recent high pressure experiments using the heat flux method demonstrated this possibility [8,14].…”

The paper presents the results that allowed obtaining the dependence of laminar flame propagation speed Sl on the equivalence ratio for a wide range of pressures and temperatures during methane combustion. A literature review was carried out to summarize the experimental data on the measurement of the Sl. The Sl was calculated using a kinetic mechanism GRI 3.0 within the required pressure and temperature range. The calculation results were generalized in the MATLAB software product to verify the Sl power dependencies on pressure and initial temperature. The results of calculation on the basis of the obtained approximating dependence were compared with the experimental data and results obtained by other authors. It was found that the exponents of power for the dependency on pressure and temperature are described not by constants or linear relations, but by second-degree equations on the fuel-air ratio. The results can be used in three-dimensional simulation of combustion processes and in calculations performed using engineering practices.
