초록
An experimental study was conducted to determine laminar burning velocity and Markstein length of SNG fuel from spherical propagating flames at normal and elevated pressure conditions. In order to make accurate results, combustion chamber was verified using methane/air mixture to find suitable extraction method and flame radius range in SNG fuel. In addition, ARAMCO 2.0 mechanism was selected to compare experimental results with numerical values. As results of this study, there were found that the laminar burning velocities and Markstein lengths of SNG fuel decreased as initial pressure rose. Pressure exponent tended to increase and decrease as the equivalence ratio increased.
