Second Moment Closure Modeling and DNS of Stratified Shear Layers
Naman Jain, Hieu T. Pham, Xinyi Huang +3
Buoyant shear layers are encountered in many engineering and environmental applications and have been studied by researchers in the context of experiments and modeling for decades.…
LES wall modeling for heat transfer at high speeds
Peng E. S. Chen, Yu Lv, Haosen H. A. Xu +2
A practical application of universal wall scalings is near-wall turbulence modeling. In this paper, we exploit temperature's semi-local scaling [Patel, Boersma, and Pecnik, {Scalar…
The diverse nature of small-scale turbulence
Ke-Qi Ding, Kun Yang, Xiang Yang +2
The self-similar Richardson cascade admits two logically possible scenarios of small-scale turbulence at high Reynolds numbers. In the first scenario, eddies' population densities…
Model-form uncertainty quantification in RANS simulations of wakes and power losses in wind farms
Ali Eidi, Reza Ghiassi, Xiang Yang +1
Reynolds-averaged Navier-Stokes (RANS) is one of the most cost-efficient approaches to simulate wind-farm-atmosphere interactions. However, the applicability of RANS-based methods…
Determining a priori a RANS model's applicable range via global epistemic uncertainty quantification
Xinyi Huang, Naman Jain, Mahdi Abkar +2
Calibrating a Reynolds-averaged Navier-Stokes (RANS) model against data leads to an improvement. Determining {\it a priori} if such an improvement generalizes to flows outside the…
