This paper presents a computational fluid dynamics (CFD) analysis of nitrogen monoxide (NO) and nitrogen dioxide (NO2) formation in a biodiesel turbulent non-premixed flame via the Eulerian-Lagrangian concept. The model includes governing conservation equations of mass, momentum and energy, and equations representing the tabulation and transport of NOX (NO+NO2). Discrete Ordinates (DO) was exploited for modeling of heat radiation that increases the accuracy of the computational simulation in the prediction of NO. The temperatures, and concentration of NOX are presented and compared with experimentation. The proposed model is able to predict the formation of NOX under many circumstances accurately. However, some discrepancies between the model and experimental data exist because of the surrogate combustion mechanism employed for biodiesel fuel and absence of prompt NO in the combustion mechanism employed in CFD codes.
