Modeling biodiesel combustion using GT-power

Research output: Contribution to conferencePaperpeer-review


A combustion model has been developed to analyze the performance and emissions of different types of diesel and biodiesel fuels. In order to have this flexibility, a new fuel library needed to be constructed. The most critical part of the fuel library construction was the use of accurate fuel properties. For this analysis, the properties of a soybean based and rapeseed based biodiesel were modeled to compare against the stock biodiesel model. The results of the combustion analysis showed that the overall cylinder pressure and maximum temperature in the cylinder were higher than for the biodiesel fuels. This led to higher values of NOx emissions. More work needs to be completed to more adequately model properties such as enthalpy in order to give a more complete and accurate analysis.
