The Unified Modeling of Acoustic Particle-Velocity Vector in Transonic Air Current

摘要：

　　In order to achieve the unified measurement of the air velocity from subsonic to supersonic circumstance,an analytical method referred to as the equivalent acoustic source,which was only suitable for the analysis of supersonic air current before,is extended to the subsonic case.Systematic analysis demonstrates the essential difference of the air current property between subsonic and supersonic scenario.Finally,a unified measurement model of acoustic particle-velocity vector is introduced.It provides a mathematical basis for us to measure the transonic air velocity via the use of an acoustic particle-velocity sensor,i.e.,acoustic vector-sensor.
