Analysis of thermal and roughness effects on the turbulent characteristics of experimentally simulated boundary layers in a wind tunnel
Demarco, Giuliano; Martins, Luis Gustavo Nogueira; Bodmann, Bardo Ernst Josef; Puhales, Franciano Scremin; Acevedo, Otávio Costa; Wittwer, Adrián Roberto; Costa, Felipe Denardin; Roberti, Débora Regina; Loredo-Souza, Acir Mércio; Degrazia, Franco Caldas; Tirabassi, Tiziano; Degrazia, Gervasio Annes (2022) [Journal article]The aim of this paper is to analyse the thermal effects in a wind tunnel experiment to simulate the planetary boundary layer (PBL). Experiments were performed in the wind tunnel of the Laboratory of Constructions Aerodynamics ... -
Comparison of CALMET and WRF/CALMET coupling for dispersion of NO2 and SO2 using CALPUFF modelling system
Schramm, Juliana; Degrazia, Franco Caldas; Vilhena, Marco Tullio Menna Barreto de; Bodmann, Bardo Ernst Josef (2016) [Journal article]This study aims to compare the wind and concentration field generated by a coupling of WRF/CALMET model and CALMET/CALPUFF with no introduction of any gridded wind field. The domain was located at the city of Linhares, ... -
Derivation of a decorrelation timescale depending on source distance for inhomogeneous turbulence in a shear dominated planetary boundary layer
Degrazia, Franco Caldas; Degrazia, Gervasio Annes; Vilhena, Marco Tullio Menna Barreto de; Bodmann, Bardo Ernst Josef (2016) [Journal article]In the literature there exists a variety of pollution of dispersion models and in general, Lagrangian stochastic models are efficient and fundamentals tools in the investigation and study of turbulent diffusion phenomenon ... -
On an air quality and odor modeling system for CMPC Celulose Riograndense
Degrazia, Franco Caldas; Bodmann, Bardo Ernst Josef (2018) [Journal article]The present work is part of the research project that aims to create an automated system for the evaluation of air pollution and odour for CMPC CELULOSE RIOGRANDENSE. Initially, three different ways of initializing the ... -
Wind tunnel experiments with neutral and convective boundary layer stabilities
Degrazia, Gervasio Annes; Bodmann, Bardo Ernst Josef; Wittwer, Adrián Roberto; Dorado, Rodrigo Martins; Degrazia, Franco Caldas; Demarco, Giuliano; Roberti, Débora Regina; Loredo-Souza, Acir Mércio; Acevedo, Otávio Costa; Martins, Luis Gustavo Nogueira (2018) [Journal article]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. ...
