• Análise experimental no túnel de vento dos processos de difusão de gases poluentes na atmosfera 

      Álvarez y Álvarez, Gisela Marina; Wittwer, Adrián Roberto; Loredo Souza, Acir Mércio (Universidade do Vale do Rio dos Sinos, 2015)
      O objetivo deste trabalho é o estudo de pro blemas de dispersão de poluentes na atmosfera em túneis de vento. A utilização de um modelo em escala reduzida fornece a capacidade de analisar o processo de dispersão em ...
    • Brazil and Argentina joint program in wind engineerind 

      Loredo Souza, Acir Mércio; Wittwer, Adrián Roberto; Rocha, Marcelo M.; De Bortoli, Mario Eduardo; Klaus Oliveira, Mario Gustavo; Marighetti, Jorge Omar (Japan Association for Wind Engineering, 2016-10)
      Research and development on Wind Engineering in Brazil and Argentina are mainly concentrated in three institutions: (i) the Laboratório de Aerodinâmica das Construções of the Universidade Federal do Rio Grande do Sul ...
    • Employing wind tunnel data to evaluate a turbulent spectral model 

      Álvarez y Álvarez, Gisela Marina; Demarco, Giuliano; Martins, Luis Gustavo; Puhales, Franciano S.; Acevedo, Otávio Costa; Loredo Souza, Acir Mércio; Bodmann, Bardo Ernst Josef; Degrazia, Gervásio Annes; Wittwer, Adrián Roberto (Science Publishing Group, 2016)
      In this study, spectra obtained from wind tunnel data are compared with a model that describes observed atmospheric neutral spectra. The investigation points out that there is a good conformity between both spectra for ...
    • Estudio experimental de las características del viento incidente sobre estructuras en caso de terrenos complejos 

      Wittwer, Adrián Roberto; Loredo Souza, Acir Mércio; Klaus Oliveira, Mario Gustavo; Marighetti, Jorge Omar; De Bortoli, Mario Eduardo (Universidade de Passo Fundo. Associação Sul Americana de Engenharia Estrutural, 2017)
      En el caso de estructuras sensibles a la acción aerodinámica, las características del viento incidente se ven modificadas por la topografía circundante provocando variaciones de las cargas aerodinámicas respecto a las ...
    • Flow in the wake of wind turbines : turbulence spectral snalysis by wind tunnel tests 

      Wittwer, Adrián Roberto; Dorado, Rodrigo; Álvarez y Álvarez, Gisela Marina; Degrazia, Gervásio Annes; Bodmann, Bardo Ernst Josef; Loredo Souza, Acir Mércio (Science Publishing Group, 2016)
      The interaction between the incident wind and wind turbines in a wind farm causes mean velocity deficit and increased levels of turbulence in the wake. The turbulent flow is characterized by the superposition of wind turbine ...
    • Study of gas turbulent dispersion process in the alcântara launch center 

      Wittwer, Adrián Roberto; Loredo Souza, Acir Mércio; Klaus Oliveira, Mario Gustavo; Fisch, Gilberto; Souza, Bianca; Goulart, Elisa (Departamento de Ciência e Tecnologia Aeroespacial, 2018-10-25)
      The Alcântara Launch Center (ALC) is the Brazilian gate to the space located at the north coast of Maranhão State, close to the Equator. Topographical local characteristics modify the parameters of incident atmospheric ...
    • Wind tunnel experiments with neutral and convective boundary layer stabilities 

      Degrazia, Gervásio Annes; Bodmann, Bardo Ernst Josef; Wittwer, Adrián Roberto; Dorado, Rodrigo; Degrazia, Franco Caldas; Demarco, Giuliano; Roberti, Débora Regina; Loredo Souza, Acir Mércio; Acevedo, Otávio Costa; Martins, Luis Gustavo (Scientific & Academic Publishing, 2018)
      The present contribution reports on the status of the STROMA experiment. As a novelty a new experimental setup in a wind tunnel allows to simulate different stability regimes with vertical heat flux in either direction. ...
