Rubio-Rodríguez Jeevan Jayasuriya Ingeniería LES combustion instantaneous velocity field resolution Large Eddy Simulation (LES) has become a powerful tool for dealing with turbulence. Nevertheless, mesh resolution of the simulated domain under the LES approach was shown to be a key matter. Critical regions should maintain an adequate mesh resolution and also the highest possible quality. LES with the Dynamic Smagorisky-Lilly sub-grid model was used for the simulation of SMA1-flame, to assess the influence of the mesh resolution on the instantaneous velocity fields, species profiles, and temperatures profiles. The results of the simulation suggest a comprehensible agreement with experimental data. Nevertheless, some areas in the highly rotational velocity field are not properly solved, mainly due to a poor mesh resolution of such areas. As a result, the central jet’s decay rate was not accurately predicted. On the other hand, the temperature and species profiles were reasonably computed, considering the simple chemistry provided by the Eddy Dissipation Model (EDM). 2023 artículo científico 0012-7353 https://www.redalyc.org/articulo.oa?id=49677978012 https://www.redalyc.org/journal/496/49677978012/ https://www.redalyc.org/journal/496/49677978012/html/ https://www.redalyc.org/journal/496/49677978012/49677978012.epub https://www.redalyc.org/journal/496/49677978012/movil https://doi.org/10.15446/dyna.v90n225.103219 en http://www.redalyc.org/revista.oa?id=496 Dyna application/pdf Universidad Nacional de Colombia Dyna (Colombia) Num.225 Vol.90 |
