The test rig, based on microwave plasma heating, is capable of achieving co-flow temperatures up to 1300 K and velocities up to 40 $$\hbox {ms}^{-1}$$ ms - 1 . Important boundary conditions at nozzle exit such as temperature, species, and velocity field were determined to prove the capabilities and limitations of the test rig. Liftoff height (LOH) measurements of $$\hbox {CH}_4$$ CH 4 , $$\hbox {C}_2\hbox {H}_4$$ C 2 H 4 , and $$\hbox {CH}_{4}/\hbox {H}_{2}$$ CH 4 / H 2 jets, propagating into a turbulent heated air co-flow, were taken using chemiluminescence imaging. Effects of the temperature and Reynolds number (Re) of co-flow and jet were also studied. Results showed that the flame stabilization mechanism is supported substantially by AI rather than pure flame propagation. While the co-flow temperature dominates the AI process, the Re and temperature of the jet just have a small impact on the LOH.
