Three-dimensional reconstruction of temperature distribution in laminar and turbulent flames from multiple interferograms

Computed tomography using two multidirectional holographic interferometers is employed to evaluate the 3D temperature distribution of an asymmetric laminar flame and a turbulent flame from an alcohol wick and a propane burner, respectively. The principles of temperature measurement are discussed, and the generation of the solid flame model is explained in terms of the interferometer measurements and the computer display. The techniques of integrated modeling and numerical simulation can be applied to analyze combustion characteristics and temperature distributions on a larger scale.
