A 3D Temperature Field Reconstruction Algorithm Based on Acoustic Travel-Time Tomography

摘要

In order to improve the reconstruction accuracy of 3D temperature field, a new 3D temperature field reconstruction algorithm based on acoustic travel-time tomography is proposed. Four typical temperature field models, i.e. one-peak symmetry model, one-peak bias model, two-peak symmetry model and four-peak symmetry model are used to verify the effectiveness of the new algorithm. 3D display of reconstructed temperature fields and reconstruction errors are given. According to the simulation result, we can conclude that the new algorithm has high reconstruction accuracy and good anti-noise ability.
