Reconstruction of Temperature Field from Sound Travel-Time Measurements: With or Without Considering the Bending of Sound Wave Paths
Commonly used acoustic reconstruction algorithms for temperature fields assume that the sound wave paths between transmitter and receiver pairs are straight.When a sound wave passes through a nonuniform temperature field,the sound wave path will bend due to refraction.A comparison study on reconstruction accuracy with and without considering the bending of sound wave paths is conducted in this paper.First,obtain a reconstruction temperature field without considering the bending of sound wave paths.Then,find the sound ray paths in the reconstructed field by developing triangular method and acquire a reconstruction field with considering the bending of sound wave paths.Various single hot temperature fields are reconstructed from sound travel-time simulation data.Suggestions are given based on the analysis of reconstruction accuracy and feature of temperature fields.
