Diesel spray model tuning and validation

A spray model has been implemented in the OpenFOAM CFD toolkit. A set of constant volume chamber injection simulations has been performed in order to analyze the influence of the spray model constants influence. In base of the performed analysis a set of model constants was selected and the simulation results were compared to the experimental results obtained on the Sandia constant volume combustion chamber. The implemented model showed very good agreement with the experimental results for what concerns vapour penetration and spray shape. The simulated liquid penetration did not match the experimental results, but it is considered less important for combustion simulations.
