  3. 12. Validation of a moderate Reynolds number channel in Neko

    Master-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Shicheng Dai; [2023]
    Nyckelord :Neko; CFD; DNS; Turbulence channel flow;

    Sammanfattning : Neko is a portable framework for high-order spectral element flow simulations[1]. Originally from Nek5000, Neko not only inherited its numerical stability and well-performance, but also added the benefits of dynamic memory and support for many current accelerator backends.
