Abstract
The present study describes the analysis of axisymmetric reactive flows using free jet liquid fuel injection with the goal of verifying the influence of fuel injection type and to estimate temperature, velocity and species concentration fields. The combustion reaction analysis is carried out for ethanol, having as oxidant the air under ambient conditions. The combustion regime considered is non-premixed. Two types of reaction mechanism were used, the mechanism of chemical kinetics considering a global, irreversible and infinite rate reaction, and the detailed chemical kinetic mechanism imported from the CHEMKIN program file. The reactive flow is solved numerically by the Finite Volume Method in a structured mesh using the ANSYS FLUENT computational code. The velocity and temperature results are compared with experimental data from the literature and show the general behavior of the adopted simulation conditions. The effect of the variation of the fuel injection type and the kinetic reaction mechanism was analyzed from the results of the concentration fields of the chemical species CO, CO2 and H2O, as well as the temperature field, respectively.
