WebMar 29, 2024 · The basic question of whether a hybrid method for turbulence simulation can plausibly capture laminar-to-turbulent transition is addressed. The $\ell ^2$ – $\omega$ adaptive detached eddy simulation model (Yin & Durbin, Intl J. Heat Fluid Flow, vol. 62, 2016, pp. 499–509) does so.It dynamically adjusts a model constant, based on local … WebSep 21, 2024 · Abstract. Detached eddy simulation (DES) and its variants are emerging tools for turbomachinery simulations. In this paper, the state-of-the-art upgrades of DES are reviewed, and their capabilities in predicting compressor tip leakage flow are discussed. The upgrade with the best potential is identified as the delayed DES (DDES) method with the …
