Summary: This work presents a computational fluid dynamics modeling of combustion with detailed chemical kinetics mechanism for incompressible laminar flow. In CFD modeling, the velocity field is obtained by solving the Navier-Stokes equations, the temperature field is obtained by solving an energy conservation equation, and the gas mixture composition is obtained by solving the conservation equations of individual chemical species a the GRI-MECH 3.0 reaction mechanism is used in the calculation of chemical kinetics. The numerical method for discretization of a generic conservation equation and the operator splitting technique used for the evaluation of chemical source terms are presented in detail. A computer code programmed in the Matlab language is used to simulate a test case and experimental data from a laminar diffusion flame of methane are used to validate the proposed CFD modeling of combustion.

Na modelagem CFD, o campo de velocidade é obtido pela solução das equações de Navier-Stokes, o campo de temperatura é obtido pela solução de uma equação de conservação da energia e a composição da mistura de gases é obtida pela solução de equações de conservação de espécies químicas individuais e o mecanismo de reação GRI-MECH 3.0 é utilizado para o cálculo da cinética química. O método numérico para discretização de uma equação genérica de conservação e a técnica de divisão de operadores usada para a avaliação dos termos de fonte químicos são apresentados em detalhes. Um código computacional programado na linguagem Matlab é utilizado para simulação de um caso de teste e dados experimentais de uma chama de difusão laminar de metano são utilizados para validação da modelagem CFD proposta.Programa de Pós-Graduação em Integridade de Materiais da Engenharia2020-12-31info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.unb.br/index.php/ripe/article/view/29958Revista Interdisciplinar de Pesquisa em Engenharia; Vol. 6 No. 2 (2020): Revista Interdisciplinar de Pesquisa em Engenharia; 81-91Revista Interdisciplinar de Pesquisa em Engenharia; v. 6 n. 2 (2020): Revista Interdisciplinar de Pesquisa em Engenharia; 81-912447-610210.26512/ripe.v6i2reponame:Revista Interdisciplinar de Pesquisa em Engenhariainstname:Universidade de Brasília (UnB)instacron:UNBporhttps://periodicos.unb.br/index.php/ripe/article/view/29958/28642Copyright (c) 2021 Revista Interdisciplinar de Pesquisa em Engenhariahttps://creativecommons.org/licenses/by-nd/4.0info:eu-repo/semantics/openAccessAlfaia da Cunha, FábioFerracuti Pierotti Ferreira, Pedro2021-01-08T16:33:15Zoai:ojs.pkp.sfu.ca:article/29958Revistahttps://periodicos.unb.br/index.php/ripePUBhttps://periodicos.unb.br/index.php/ripe/oaianflor@unb.br2447-61022447-6102opendoar:2021-01-08T16:33:15Revista Interdisciplinar de Pesquisa em Engenharia - Universidade de Brasília (UnB)false
