RANS Turbulence Model Development using CFD-Driven Machine Learning [PDF]
J. Comp. Phys., Vol. 441, (2020) 109413, 2019 This paper presents a novel CFD-driven machine learning framework to develop Reynolds-averaged Navier-Stokes (RANS) models. The CFD-driven training is an extension of the gene expression programming method (Weatheritt and Sandberg, 2016), but crucially the fitness of candidate models is now evaluated by running RANS calculations in an integrated way ...

CFD: an efficient active queue management algorithm with CFD
Electronics Letters, 2016 The existence of the bufferbloat and high‐bandwidth non‐adaptive flows results in the high queuing delay, which affects the performance of interactive applications, and the inter‐flow unfairness, respectively. To solve above‐mentioned issues, an efficient active queue management algorithm with Controlling Fairness and Delay (CFD) is proposed. Different
