Computed tomography (CT) has the potential to greatly enhance our understanding of the turbulent flow structures, the combustion chemistry, and the interactions between the two, which challenge us in our attempts to understand and model the details of turbulent combustion. Here, we present high-resolution and fully three-dimensional measurements of the flame surface of a turbulent reacting flow. The CT-reconstructed images show the flame front, at a single instant in time, of a turbulent, premixed propane/air flame. The significance of this powerful experimental tool is to provide new insight into turbulent combustion, allowing for the development of cleaner burning, higher power, and more efficient combustors.
