Simulation of Temperature Field Reconstruction by Acoustic Based on Improved Landweber Method

Abstract

Temperature measurement by acoustic is a new kind of temperature visualization measurement technology. It is very important to develop three-dimensional temperature field reconstruction algorithm in acoustic application. In order to get the three-dimensional temperature field distribution, this paper presents to reconstruction the temperature field distribution by Landweber method. A preprocessing matrix is adopted to accelerate the method according to the characteristics of temperature field. Based on several typical distribution model of temperature field simulation, The results show that the algorithm of Landweber and precondition matrix method can realize the reconstruction of the temperature field.
