A CFD framework for offshore and onshore wind farm simulation
(IOP Publishing, 2017)
Article.
Accés obert
Article.
Accés obert
We present a wind simulation framework for offshore and onshore wind farms. The simulation framework involves an automatic hybrid high-quality mesh generation process, a pre-processing to impose initial and boundary ...
Multi-objective scheduling of Scientific Workflows in multisite clouds
(Elsevier, 2016-10)
Article.
Accés obert
Article.
Accés obert
Clouds appear as appropriate infrastructures for executing Scientific Workflows (SWfs). A cloud is typically made of several sites (or data centers), each with its own resources and data. Thus, it becomes important to be ...
The combustion mitigation of methane as a non-CO2 greenhouse gas
(Elsevier, 2018-05)
Article.
Accés obert
Article.
Accés obert
Anthropogenic emissions of non-CO2 greenhouse gases such as fugitive methane contribute significantly to global warming. A review of fugitive methane combustion mitigation and utilisation technologies, which are primarily ...
Toward an automatic full-wave inversion: Synthetic study cases
(Society of Exploration Geophysicists, 2016-12)
Article.
Accés obert
Article.
Accés obert
Full-waveform inversion (FWI) in seismic scenarios continues to be a complex procedure for subsurface imaging that might require extensive human interaction in terms of model setup, constraints, and data preconditioning. ...
Parallel mesh partitioning based on space filling curves
(Elsevier, 2018-09)
Article.
Accés obert
Article.
Accés obert
Larger supercomputers allow the simulation of more complex phenomena with increased accuracy. Eventually this requires finer and thus also larger geometric discretizations. In this context, and extrapolating to the Exascale ...
Mesh generation, sizing and convergence for onshore and offshore wind farm Atmospheric Boundary Layer flow simulation with actuator discs
(Elsevier, 2018-12)
Article.
Accés obert
Article.
Accés obert
A new mesh generation process for wind farm modeling is presented together with a mesh convergence and sizing analysis for wind farm flow simulations. The generated meshes are tailored to simulate Atmospheric Boundary Layer ...
Acceleration strategies for elastic full waveform inversion workflows in 2D and 3D
(Springer International Publishing, 2017-02-01)
Article.
Accés obert
Article.
Accés obert
Full waveform inversion (FWI) is one of the most challenging procedures to obtain quantitative information of the subsurface. For elastic inversions, when both compressional and shear velocities have to be inverted, the ...
A wind field downscaling strategy based on domain segmentation and transfer functions
(Wiley, 2018-02-06)
Article.
Accés obert
Article.
Accés obert
This paper presents a novel methodology for mesoscale‐to‐microscale downscaling of near‐surface wind fields. The model chain consists on the Weather Research and Forecast mesoscale model and the Alya‐CFDWind microscale ...
Optimization strategies for geophysics models on manycore systems
(2019-01-17)
Article.
Accés obert
Article.
Accés obert
Many software mechanisms for geophysics exploration in oil and gas industries are based on wave propagation simulation. To perform such simulations, state-of-the-art high-performance computing architectures are employed, ...
Diurnal cycle RANS simulations applied to wind resource assessment
(Wiley, 2019-02)
Article.
Accés obert
Article.
Accés obert
Microscale computational fluid dynamics (CFD) models can be used for wind resource assessment on complex terrains. These models generally assume neutral atmospheric stratification, an assumption that can lead to inaccurate ...
