El present treball exposa un estudi avançat de la resolució numèrica de les equacions multidimensionals de Navier-Stokes mitjançant mètodes computacionals. El projecte ha constat d’un detallat anàlisi teòric, a partir del ...

Approximate Bayesian Computation (ABC) method is used to estimate posterior distributions of model parameters in subgrid-scale (SGS) closures for large eddy simulations (LES) of turbulent flows. The ABC approach avoids the ...

The aim of this project is to find the correlation between turbulence intensity and acoustic noise level. To achieve this aim a test was performed on the 5th of April 2012 in the acoustic laboratory of the Technical ...

There is a growing number of wind turbines installed in cold temperature zones as a result of the restricted space for new construction. Due to ice deposition on the turbine blades, the increasing installation of wind ...

Traditionally turbulence modeling of industrial flows in complex geometries have been solved using RANS models and unstructured meshes based solvers. The lack of precision of RANS models in these situations and the increase ...

As new supercomputer architectures become more heavily focused on using hardware accelerators, in particular general-purpose graphical processors, it is therefore relevant that algorithms for computational fluid dynamics, ...

A novel framework for a 5-term explicit algebraic Reynolds stress model has been proposed, which is suitable for machine learning procedures. Under this framework, high-fidelity datasets have been explored and post-processed. ...

A large eddy simulation (LES) of the flow past a 30P30N high-lift three-element wing is performed at the angle of attack AoA = 9º and a Reynolds number of Re = 750,000, based on the nested chord. Results are validated ...
