In this study, a chemical reaction mechanism reduction was performed to address lengthy simulation times resulting from the complex chemical structure of the chemical reaction mechanism that is used in simulating the oxidation process of fuel in combustion simulations. Mechanism reduction was achieved by removing the chemical species and reaction equations that were considered low in importance in the chemical reaction mechanism. Likewise, mechanism synthesis and coupling were performed for soot calculation. However, errors occurred in the simulation results due to the removal of the chemical species and reaction equations. Therefore, the pre exponential factor of the Arrhenius equation was adjusted to improve accuracy. Thus, a reduced chemical reaction mechanism for biodiesel was developed, resulting in a 9.54 % error for soot, 4.14 % error for NOX, and 9.2 % deviation for IMEP. |
