Two-Dimension Temperature Field Reconstruction in Furnace by Acoustic Method

Abstract:

Acoustic temperature measurement technology is a new temperature measuring technology which is rising in recent years. This paper discusses a kind of reconstruction method of temperature field based on acoustic pyrometer. First , acoustic sensors has been used to obtain measurement data, and the technique of wavelet has been used to denoise in order to improve the accuracy of measurement , secondly, the least-squares algorithm has been used to reconstruct temperature field. Finally, we work out our own acoustic temperature measurement system and has got the satisfying result using our own acoustic pyrometer to detect two-dimension temperature field in the laboratory.
