Acoplamiento del modelo regional de calidad de aire (CMAQ) con el modelo de emisiones locales mediante elementos finitos
(2009-06-08T09:47:57Z)
Conference report
Open AccessExisten modelos regionales de calidad del aire que son muy utilizados. Estos modelos tienen modelos para estudiar el aporte de contaminantes provocados por fuentes importantes de contaminación, como pueden ser chimeneas, ... -
Adaptive finite element simulation of stack pollutant emissions over complex terrains
(2013-01-01)
Article
Open AccessA three-dimensional finite element model for the pollutant dispersion is presented. In these environmental processes over a complex terrain, a mesh generator capable of adapting itself to the topographic characteristics ... -
Approximation of immersed surfaces into a tetrahedral mesh generated by the meccano method
(2017)
Conference report
Restricted access - publisher's policyIn this paper, we present a new method to insert open surfaces into an existing tetrahedral mesh generated by the meccano method. The surfaces must be totally immersed in the mesh and must not intersect between them. The ... -
Finite element simulation of a local scale Air Quality Model over complex terrain
(2012)
Article
Open AccessIn this paper we propose a finite element method approach for modelling the air quality in a local scale over complex terrain. The area of interest is up to tens of kilometres and it includes pollutant sources. The proposed ... -
Insertion of triangulated surfaces into a meccano tetrahedral discretization by means of mesh refinement and optimization procedures
(John Wiley & Sons, 2018)
Article
Open AccessIn this paper, we present a new method for inserting several triangulated surfaces into an existing tetrahedral mesh generated by the meccano method. The result is a conformal mesh where each inserted surface is approximated ... -
Local scale air quality model system for diagnostic and forecasting simulations using the finite element method
(Universitat Politècnica de Catalunya, 2015-11-13)
Doctoral thesis
Open AccessAir pollution is an important topic with a great social impact; it is related with public health, environment and ecology, and climate change. Scientists have developed several models in the last thirty years, and regional ... -
Simulating large emitters using CMAQ and a local scale finite element model: analysis in the surroundings of Barcelona
(2016)
Conference lecture
Open AccessIn this work, we compare two state of the art models to simulate large emitters in the local scale. The area of study is in the surroundings of Barcelona, where an important contributor to the SO2 levels is considered. The ... -
Simulating large emitters using CMAQ and a local scale finite element model: analysis of the surroundings of Barcelona
(2017)
Article
Open AccessIn this work, we present a novel approach to simulate large emitters in the microscale. The main idea is to combine a nested grid approach and a finite element model to simulate the subgrid scale. The nested grid system ...
