- Summary:
- The OpenFOAM® CFD methodology is nowadays employed forsimulation in internal combustion engines and a lot of work hasbeen done for an appropriate description of all complex phenomena.At the moment in the RANS turbulence models available in theOpenFOAM® toolbox the turbulence modulation is not yet included,and the present work analyzes the predictive capabilities of thecode in simulating high injection pressure fuel sprays aftermodeling the influence of the dispersed phase on the turbulencestructure.Different experiments were employed for the validation. Atfirst, non-evaporating diesel spray was considered in a constantvolume and quiescent vessel. The validation was performed via theavailable experimental spray evolution in terms of penetrations andspatial/temporal fuel distributions. Then the Sandia combustionchamber was chosen for diesel spray simulation in non-reactingconditions. The effect of turbulence modulation was analyzed interms of liquid and vapor penetrations, turbulent viscosity andintensity adopting different sets of spray sub-models to evaluatethe relative influence of turbulence modulation by varyingatomization and breakup models.Simulations show that turbulence modulation modeling produces,as the main effect of particles on the continuous gas phase, anenhancement of the gas turbulent intensity and vapor diffusion. Inany case the proposed approach should be able to correctly simulatethe mixture formation process of a diesel fuel spray
