Abstract:
A tridirectional large lateral shearing displacement interferometric system has been proposed and used to reconstruct the temperature field of a quasi-axisymmetric diffused ethylene flame in two-dimensional (2D) and three-dimensional (3D) hypotheses. In comparison with the thermocouple results, the 2D reconstructed results affords a quantitative analysis with an average discrepancy between 20 and 40 K in the full field, except in the closer part inside the peak temperature location where a high soot volume fraction exists. The 3D reconstructed results affords qualitative analysis and exhibits some asymmetrical characters, but an obvious error occurs at 1 cm height where it is not suitable to use the universal correction coefficient.
