    AI techniques in CFD: leveraging physical priors with deep learning to improve on numerical solvers by Loh, Jessica Sher En

    Published 2025
    “…Additionally, it extends the use of residual training to improve flow field prediction for a GNN scenario with immersed object, when low resolution data is available. Lastly, the third part aims to enhance flow predictions around complex geometries, which may often be deconstructed into multiple, simple bodies, by leveraging existing data on these single geometry flow fields. …”

    A combined numerical and experimental approach to investigations of body-freedom flutter on flying wings by Ang, Elijah Hao Wei

    Published 2024
    “…BTF and BFF experience different dominant modes while undergoing flutter, with BTF’s dominant mode being torsion and BFF being the rigid-body short period mode, resulting in lower BFF speeds when compared to BTF. In general, BTF speeds increase as weights are moved towards the wingtip or increasing tip weights, which increases the inertia of the system to enhance stability. …”
