On the morphodynamics of a wide class of large-scale meandering rivers: Insights gained by coupling LES with sediment-dynamics
Ali Khosronejad, Ajay B. Limaye, Zexia Zhang +3
In meandering rivers, interactions between flow, sediment transport, and bed topography affect diverse processes, including bedform development and channel migration. Predicting ho…
Onset of wake meandering for a floating offshore wind turbine under side-to-side motion
Zhaobin Li, Guodan Dong, Xiaolei Yang
Wind turbine's wake, being convectively unstable, may behave as an amplifier of upstream perturbations and make the downstream turbine experience strong inflow fluctuations. In thi…
A single formula for the law of the wall and its application to wall-modelled large-eddy simulation
Fengshun Zhang, Zhideng Zhou, Xiaolei Yang +1
In this work, we propose a single formula for the law of the wall, which is dubbed as the logarithmic-exponential (LOG-EXP) formula, for predicting the mean velocity profile in dif…
Similarity of wake characteristics for yawed wind turbines of utility-scale
Zhaobin Li, Xiaolei Yang
This work is dedicated to studying the influence of yaw angle on the wake characteristics of a 2.5 MW utility-scale wind turbine using large-eddy simulations with the turbine's bla…
A wall model based on neural networks for LES of turbulent flows over periodic hills
Zhideng Zhou, Guowei He, Xiaolei Yang
In this work, a data-driven wall model for turbulent flows over periodic hills is developed using the feedforward neural network (FNN) and wall-resolved LES (WRLES) data. To develo…
On the wake meandering of a model wind turbine operating in two different regimes
Daniel Foti, Xiaolei Yang, Filippo Campagnolo +2
The flows behind a model wind turbine under two turbine operating regimes are investigated using wind tunnel experiments and large-eddy simulations. Measurements from the model win…
A new class of actuator surface models for wind turbines
Xiaolei Yang, Fotis Sotiropoulos
Actuator line model has been widely employed in wind turbine simulations. However, the standard actuator line model does not include a model for the turbine nacelle which can signi…
Coherent dynamics in the rotor tip shear layer of utility scale wind turbines
Xiaolei Yang, Jiarong Hong, Matthew Barone +1
Recent field experiments conducted in the near-wake (up to 0.5 rotor diameters downwind of the rotor) of a 2.5 MW wind turbine using snow-based super-large-scale particle image vel…
