The current study investigates the evolution of flame geometry, average mass burning rates, and puffing frequency in wind-driven flames subjected to turbulent crossflow conditions. Grid-generated turbulence was used to introduce freestream turbulence into the incoming flow. Results reveal that increasing freestream turbulence intensity (TI) significantly distorts flame structure, manifesting as wrinkles, fluctuations, flame fragmentation, and curling behavior. With higher freestream turbulence intensity, flame length and flame attachment length decreased, while flame height exhibited an inconsistent trend. The average mass burning rate increased with both crossflow velocity and freestream turbulence. The mixed-convection parameter (ξ) was used to characterize the collective effects of flow momentum, buoyancy, and freestream turbulence on global mass burning rates, leading to an empirical correlation. The chaotic nature of turbulence also influenced puffing behavior, with puffing frequency increasing with an increase in crossflow velocity and turbulence levels.
