WebFeb 1, 2009 · The other two models, respectively, based on the original k–ε model (KE) and the renormalized group k–ε model (RNG), are mutually reinforcing but lie higher than both the data and the REAL predictions. On this basis, it appears reasonable to select the REAL model for future calculations involving distribution manifolds of the type being ... WebApr 10, 2024 · Minimal dimensional models are desirable for reduced computational costs in simulations as well as for applications such as model-based control. Long-time dynamics of flows often evolve on a low-dimensional manifold M in the full state space. We use neural networks to estimate M and the dynamics on it for two-dimensional Kolmogorov flow in a …
