Evaluation of the discretization in the spectral resolution for the solution of the line‑by‑line method in problems with participating gases
(2019) [Journal article]Despite the complexity to solve problems involving radiation heat transfer in participating media, especially due to the strong spectral dependence of the absorption coefcient, thermal radiation cannot be neglected in ... -
Hybrid system simulation to supply heated air to a solar food dryer
(2020) [Journal article]The intermittence of solar radiation, due to continuous rainy or cloudy days, is a limitation of simple and small solar dryers. These conditions often make them impossible to use. By including storage systems (thermal ... -
Limitations of simplifed models to predict soot formation in laminar flames
(2020) [Journal article]Soot formation and radiation are important aspects for combustion problems. In this work, numerical simulations of ethylene cofow laminar flames are used to evaluate soot formation and radiation processes under diferent ... -
A numerical study of the influence of radiation on turbulence in a 2D axisymmetric turbulent flame
(2015) [Journal article]This paper presents a study of the influence of thermal radiation on turbulence in the simulation of a turbulent, non-premixed methane- air flame. In such a problem, two aspects need to be considered for a precise evaluation ...
