(Universidad Nacional de ColombiaBogotá - Ingeniería - Maestría en Ingeniería - Automatización IndustrialDepartamento de Ingeniería Eléctrica y ElectrónicaFacultad de IngenieríaBogotáUniversidad Nacional de Colombia - Sede Bogotá, 2021-05-31)
Los Túneles de Viento son una herramienta para la simulación del flujo del aire en diferentes aplicaciones, de tal manera que se puedan realizar pruebas y simulaciones de modelos a escala, reduciendo los costos. En este ...
Wind farm interference and terrain interaction simulation by means of an adaptive actuator disc
(Elsevier Science, 2019-03)
Wind turbine wake interference is a relevant phenomenon that involves speed losses and turbulence increments which greatly affect downstream turbines, and power efficiency of wind farms. To precisely simulate wake interaction, ...
Modelagem e simulação da estratificação térmica na camada limite atmosférica
(Universidade do Vale do Rio dos Sinos, 2021-09-30)
Simulations of wind flow in the atmospheric boundary layer currently carried out, despite being well developed, often disregard effects such as the different thermal stratification conditions, in order to simplify the ...

Simulações em laboratório de escoamentos em meios estratificados
(Universidade Federal de Santa MariaBRFísicaUFSMPrograma de Pós-Graduação em Física, 2013-10-02)
In the present thesis, two distinct scientific problem in fluid mechanics are studied using
laboratory observation techniques. In the first of them, a tank was used to simulate microburst
propagation. In the experimental ...
Reviewing the art of modeling 3D aeroelastic behavior of cable-stayed bridges
(2015-06-21)
The development of an optimized structural design and the calculation of dynamic internal forces in the complete structure of a cable-stayed bridge under wind action is properly carried out with a theoretical-computational ...
PM10 emission efficiency for agricultural soils: Comparing a wind tunnel, a dust generator, and the open-air plot
(Elsevier, 2018)
The PM10 emission efficiency of soils has been determined through different methods. Although these methods
imply important physical differences, their outputs have never been compared. In the present study the PM10
emission ...
A study of the internal boundary layer generated at the Alcantara Space Center
(Scientific and Academic PublishingRosemead, CA, 2015)
An atmospheric Internal Boundary Layer (IBL) occurs when sudden changes in surface roughness disturb
wind flows. The region of the Brazilian Alcantara Space Center (ASC), with its rocket launching pad located 150 m
downwind ...
