title = "Simultaneous 2-l OH thermometry and PIV of unsteady methane-air kernel-vortex interactions",
abstract = "Methane kernel-vortex interactions have been studied using partial image velocimetry (PIV) and 2-l OH thermometry to determine the aerodynamic conditions necessary to produce viable combustion. Three vortex rotational velocities (strengths) have been categorized to explore a range of fluidic motion from completely laminar to transitional. Derived from the 2-D PIV velocity profiles, the strain rate along the edge of the flame-vortex interface has been determined for each of the three vortex strengths. While these results are preliminary, there is a significant increase in the maximum strain rate each kernel undergoes as the strength of the vortex increases. With an increase in vortex rotational velocity of 250% (weak to medium strengths) there is a 60% increase in maximum strain rate, while a 400% increase in vortex rotational velocity (weak to strong) shows a 120% increase in maximum strain rate over the times observed. Thermometry results show an increase in maximum average kernel temperature across the time of interest of 3%, 14% and 19% for the weak vortex, the medium vortex and the strong vortex respectively when compared to the undisturbed kernel.",
