Determination and introduction of the transport properties of soybean oil biodiesel in the CFD code OpenFOAM

ABSTRACT
In this work the determination and introduction of the transport properties of soybean oil biodiesel in the Computational Fluid Dynamics code OpenFOAM has been studied. Additionally, effects of soybean oil biodiesel on the mixing process using Computational Fluid Dynamics code OpenFOAM have been analyzed. In order to reach the objectives previously described, the most relevant transport properties of soybean oil biodiesel in the mixing process i.e. density, viscosity, surface tension and vapor pressure have been determined. These transport properties were introduced in the Computational Fluid Dynamics code OpenFOAM using coefficients obtained, which are based on the molecular structure of the fatty acids that composes the biodiesel and applying nonlinear regressions. The main findings of the work were: (1) the coefficients which are used in the proposed models by Computational Fluid Dynamics code OpenFOAM for the introduction of the transport properties of soybean oil biodiesel have been obtained, (2) the influence of the transport properties of soybean oil biodiesel on the mixing process has been confirmed.
