Abstract: 

Spar ignition in turbulent methane-air jet is studied by a compressible 3D Large Eddy Simulation in Open FOAM code. The thicened flame model with the one-step chemical mechanism is used for methane combustion. The spar is modeled by artificial enthalpy source in energy equation at the spar location. The validation of the calculations is performed using the experimental results of the turbulent jet of airflow and non reacting mixing of methane jet. The ignition phenomenon and flame propagation are investigated in details for different conditions of initial jet temperature. The results show that the flame propagation speed, the flame lift-off and the flame distance to the axis change with changing the initial temperature.
