Reconstruction of the Flow Cross-Section Temperature Based on the Radiation Balance Between Infinitesimal

Abstract:

The reconstruction of three-dimensional temperature field is a difficult problem. But three-dimensional temperature measurement can be simplified by the reconstruction of the flow cross-section temperature. In this paper, a theory of reconstruction is proposed and a simulation test system is implemented by MATLAB based on emission spectra tomography (EST) and radiation temperature measurement, which also take the emission and absorption characteristics in the processing of radiative transfer under consideration. Finally, by analyzing the difference of the original temperature and reconstructed temperature we can get the accuracy of the reconstruction theory.
