| description |
This paper deals with the influence of concrete structures on atmospheric temperatureand the convection winds generated in the Aburra Valley in Medell´ın,Colombia. This area is characterised by low wind velocities with a high industrydensity. A digital elevation model was used from the Radar ShuttleTopography Mission and post-processed in order to obtain a valid volumetricCFD domain. The construction process includes hole-filling due to imperfectionsin the original radar data, decimation of the original cloud-of-points to reduce the excess of detail in regions with low curvature, and the introductionof a volume of air over the terrain surface (CFD domain). Landsat satellitedata was used to set the terrain temperatures for various material compositions.The converted infrared image was then registered into the CFD domainusing an interpolation technique. |

Esta área se caracteriza por bajas velocidades del viento con una alta densidad industrial. Se usó un modelo de elevación digital de la Misión Radar ShuttleTopography y se procesó posteriormente para obtener un dominio de CFD volumétrico válido. El proceso de construcción incluye el llenado de agujeros debido a imperfecciones en los datos de radar originales, la destrucción de la nube de puntos original para reducir el exceso de detalle en regiones con baja curvatura y la introducción de un volumen de aire sobre la superficie del terreno (dominio CFD ) Los datos de satélite Landsat se usaron para establecer las temperaturas del terreno para diversas composiciones de materiales. La imagen infrarroja convertida se registró luego en el dominio CFD utilizando una técnica de interpolación.application/pdfengUniversidad EAFIThttp://publicaciones.eafit.edu.co/index.php/ingciencia/article/view/214http://publicaciones.eafit.edu.co/index.php/ingciencia/article/view/214Copyright (c) 2008 Manuel Julio García, Pierre Boulanger, Juan Duque, Santiago GiraldoAcceso abiertohttp://purl.org/coar/access_right/c_abf2instname:Universidad EAFITreponame:Repositorio Institucional Universidad EAFITIngeniería y Ciencia; Vol 4, No 8 (2008)CFD Analysis of the Effect on Buoyancy Due to Terrain Temperature Based on an Integrated DEM and Landsat Infrared ImageryAnálisis CFD de vientos convectivos naturales debidos a la temperatura de un terreno basado en un modelo DEM integrado con imágenes infrarrojas Landsatarticleinfo:eu-repo/semantics/articlepublishedVersioninfo:eu-repo/semantics/publishedVersionArtículohttp://purl.org/coar/version/c_970fb48d4fbd8a85http://purl.org/coar/resource_type/c_6501http://purl.org/coar/resource_type/c_2df8fbb1BuoyancyLandsatDigital Elevation ModelsComputational Fluid DynamicsFlotabilidadLandsatModelos Digitales De ElevaciónDinámica De Fluidos ComputacionalGarcía, Manuel JulioBoulanger, PierreDuque, JuanGiraldo, SantiagoEAFIT UniversityUniversity of AlbertaEAFIT UniversityEAFIT UniversityIngeniería y Ciencia486584ing.cienc.ORIGINAL4.pdf4.pdfTexto completo PDFapplication/pdf615441https://repository.eafit.edu.co/bitstreams/e783a7f7-fcaf-4db4-85a9-2faa73c00cd6/download9e6a86c18c3f7859ba740191f79f75faMD52articulo.htmlarticulo.htmlTexto completo HTMLtext/html373https://repository.eafit.edu.co/bitstreams/239e04f1-9b92-4d07-ae74-19cd0814f840/downloadb51250765f0f039b57536bb35471ff0bMD53THUMBNAILminaitura-ig_Mesa de trabajo 1.jpgminaitura-ig_Mesa de trabajo 1.jpgimage/jpeg265796https://repository.eafit.edu.co/bitstreams/cd611850-7aba-47cc-97d4-3f63226465f3/downloadda9b21a5c7e00c7f1127cef8e97035e0MD5110784/14520oai:repository.eafit.edu.co:10784/145202020-03-02 23:04:48.277open.accesshttps://repository.eafit.edu.coRepositorio Institucional Universidad EAFITrepositorio@eafit.edu.co |
