Study on Reconstruction Algorithm of Two-Dimensional Temperature Field Based on Simulation of Sound Propagation Path

摘要：

The acoustic ray refraction on measuring temperature field of large-scale coal-fired power plant furnace is an important factor affects the accuracy of measuring the temperature field,If can simulate the propagation of the true path of the acoustic waves will further enhance the accuracy of the reconstruction of temperature field. This paper proposes a two-dimensional temperature field reconstruction algorithm simulates the sound propagation path based on the least-squares algorithm. This algorithm considers the bending effect of the sound propagation path,through the interpolation method to simulate the actual sound propagation path. The simulation result shows that the algorithm can corrected the curved sound path automatically and reconstructed the temperature field simultaneously. Compare with the least-squares algorithm,this algorithm can significantly improve measurement accuracy.
