Methane and propane kernel-vortex interactions have been investigated using high-speed chemiluminescence imaging coupled with simultaneous global pressure measurements. Highly repeatable vortex generation and reactant equivalence ratio have allowed a direct comparison between a variety of vortex strengths and reactant mixtures. Characterized as "weak", "medium" and "strong", the vortices are timed to interact with a variety of sizes of kernels (based on time since ignition). High-speed chemiluminescence images have shown a general geometric increase in kernel area and therefore reactant consumption rate. Simultaneous pressure measurements show a global increase in rate of pressure rise when burning is augmented with a vortex. Also, the effect of vortex strength on global kernel geometry can, in some cases, be directly observed through the pressure measurements. Simultaneous effective radius and pressure measurements allow the determination of local, instantaneous laminar flame speed, which gives particular insight into the effects of vortex augmentation.
