Large eddy simulation and laboratory experiments on the decay of grid wakes in strongly stratified flows
(2009-07-27)
Article
Accés obertA detailed analysis of the flow structure resulting from the combination of turbulence and internal waves is carried out and visualized by means of the Schlieren method on waves in a strongly stratified fluid at the ... -
MicroHH 1.0: a computational fluid dynamics code for direct numerical simulation and large-eddy simulation of atmospheric boundary layer flows
(2017-08-28)
Article
Accés obertThis paper describes MicroHH 1.0, a new and open-source (www.microhh.org) computational fluid dynamics code for the simulation of turbulent flows in the atmosphere. It is primarily made for direct numerical simulation but ... -
On the dynamics of the turbulent flow past a three-element wing
(2024-02-12)
Article
Accés obertA comprehensive analysis of the unsteady flow dynamics past the 30P30N three-element high lift wing is performed by means of large eddy simulations at different angles of attack (AoA=5°, 9°, and 23°) and at a Reynolds ... -
Regularization modeling of wall-bounded turbulent flows
(2010)
Comunicació de congrés
Accés restringit per política de l'editorialSince direct numerical simulations cannot be computed at high Reynolds numbers, a dynamically less complex formulation is sought. In the quest for such a formulation, we consider regularizations of the convective term ... -
Towards stochastic methods in CFD for engineering applications
(Universitat Politècnica de Catalunya, 2021-12-21)
Tesi
Accés obertRecent developments of high performance computing capabilities allow solving modern science problems employing sophisticated computational techniques. However, it is necessary to ensure the efficiency of state of the art ... -
Turbulent flow in a differentially heated cavity: direct numérical simulation and regularization modeling
(2010)
Comunicació de congrés
Accés restringit per política de l'editorialWe consider regularizations of the convective term that preserve symmetry and conservation properties exactly. This yields a novel class of regularizations that restrain the convective production of small scales in an ...
