On the interaction of fish and marine hydrokinetic turbines: Insights gained through experimental and computational observations
Hossein Seyedzadeh, Mehrshad Gholami Anjiraki, Guglielmo Sonnino Sorisio +3
Tidal and riverine hydrokinetic turbines offer promising solutions for renewable energy generation in aquatic environments. However, their ecological impact, especially on fish beh…
Toward ultra-efficient high-fidelity prediction of bed morphodynamics of large-scale meandering rivers using a novel LES-trained machine learning approach
Zexia Zhang, Mehrshad Gholami Anjiraki, Hossein Seyedzadeh +2
Flood-induced deformation of the bed topography of fluvial meandering rivers could lead to river bank displacement, structural failure of the infrastructures, and the propagation o…
Toward ultra-efficient high fidelity predictions of wind turbine wakes: Augmenting the accuracy of engineering models via LES-trained machine learning
Christian Santoni, Dichang Zhang, Zexia Zhang +3
This study proposes a novel machine learning (ML) methodology for the efficient and cost-effective prediction of high-fidelity three-dimensional velocity fields in the wake of util…
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…
A computational study of expiratory particle transport and vortex dynamics during breathing with and without face masks
Ali Khosronejad, Seokkoo Kang, Fabian Wermelinger +2
We present high-fidelity numerical simulations of expiratory biosol transport during normal breathing under indoor, stagnant air conditions with and without a facial mask. We inves…
Fluid dynamics simulations show that facial masks can suppress the spread of COVID-19 in indoor environments
Ali Khosronejad, Christian Santoni, Kevin Flora +4
The Coronavirus disease outbreak of 2019 has been causing significant loss of life and unprecedented economical loss throughout the world. Social distancing and face masks are wide…
Dynamic vortical flow profile quantitatively characterizes mitral valvular-left ventricular hemodynamic coupling: In vivo analysis by dynamic 3D enstrophy mapping from 4D Flow MRI
Mohammed S. M. Elbaz, Trung Bao Le, Pankaj Garg +6
Vortical blood flow in the human left ventricular (LV) inflow initiates from the mitral valve (MV) and evolves within the LV during diastolic E-filling. Hence, vortical flow links…
Multi-resolution large-eddy simulation of an array of hydrokinetic turbines in a field-scale river: The Roosevelt Island Tidal Energy project in New York City
Saurabh Chawdhary, Dionysios Angelidis, Jonathan Colby +3
Marine hydrokinetic (MHK) power generation systems enable harvesting energy from waterways without the need for water impoundment. A major research challenge for numerical simulati…
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…
Vortex rings from notched nozzles
Trung Bao Le, Fotis Sotiropoulos
The formation of a vortex ring from a piston/nozzle apparatus depends on the nozzle exit's shape. Here we study the formation mechanism and the evolution of asymmetrical rings from…
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…
