Some studies showed that an ultrasonically absorptive coating (UAC) can suppress the second instability thereby delay the transition of hypersonic boundary layer. A theoretical model is employed to analyze and compare the reflection behaviors of UAC cavities by keeping constant porosity φ and cavity...
