To developing new instability suppression methods and compare the accuracy and computation cost of the proposed methods with previous methods.
In this case, a time-harmonic acoustic wave propagates across a 2- D domain, and the sound is refracted across a finite shear layer. The solution field obtained the LEE is clearly contaminated by the numerical instability, while the proposed ADT method can an untouched acoustic filed.
In this case, a time-harmonic acoustic wave propagates across a 2- D domain, and the sound is refracted across a finite shear layer. Comparing with the LEE solution, where the K-H instabilities appears and large spurious wave can be observed, the proposed method can provide uncontaminated results in acoustics near field and far field.
