Abstract

This present work shows a study of the effect of thermal radiation in the simulation of a turbulent, non-premixed diesel-air, hydrogen-air, kerosene-air, n-butanol, pentane-air, propane-air and methane–air used in a 2D geometry cylindrical combustion chamber. The numerical simulation based on the solution of the mass, momentum, energy and the chemical species conservation equations was performed for steady state condition using computation Fluid Dynamic (CFD), while the turbulence modeling was considered via standard k–ε model. The results indicate that highest mass fraction of NO emissions with hydrogen-air fuel compared to diesel fuel. The results showed a better performance of kerosene-air alternative based on the emissions characteristics in the present work. The CO2 emission reduced with hydrogen-air compared to diesel fuel due to better combustion. A significant decrease of emissions characteristics (O2, H2O and NO) was observed. The present numerical investigated results of methane-air are compared to experimental results compared to Silva et al. (2007) and Garreton and Simonin (1994) for tool validation.
