DOI: 10.1063/5.0290084
Abstract: Pitot probes are commonly used for characterizing freestream disturbances in supersonic and hypersonic wind tunnels. However, disturbance resonance between the detached shock and probe surface prevents Pitot pressure from representing true post-shock stagnation pressure fluctuations,… read more here.

DOI: 10.3390/sym17111923
Abstract: To address challenges in holistic real-time condition monitoring of conventional wind tunnels—caused by large structural dimensions and complex parameter monitoring—this study proposes a wind tunnel condition monitoring surrogate model (POD-BPNN) integrating Proper Orthogonal Decomposition (POD)… read more here.
