Summary:Aiming at the effect of species composition distribution on flow field's temperature reconstruction from the experimentally measured refractive index, a temperature partition reconstruction method based on flow field's phase distribution is proposed. Moiré deflection tomography is chosen to obtain the refractive index of a flame with probe wavelength of 808nm. Enlightened by the visual characteristic of optical computerized tomography (OCT) for flow field and the practical structure of the flame, it is divided into three regions in radial direction based on its phase distribution. The essence is that the temperature is reconstructed with adopting different species composition for different regions. Finally, the rationality of the method is analyzed.
