- Summary:
- The morphology of the internal flow of Spray C was numerically investigated using an Eulerian method (Volume of Fluid) in the finite-volume framework. X-ray measured injector geometry from the Engine Combustion Network was employed to set up the boundary condition. Simulations were performed under a hot and high-pressure ambient condition, 900 K and 60 bar. Three instantaneous events were modeled, including the initial nozzle opening, steady, and nozzle closing events. First, a grid-convergent study was performed. It demonstrated that the predicted cavitation formation process was significantly affected by various grid sizes. A minimum mesh size of 7.8 m was needed to reproduce properly the experimental observation. An area coefficient (Ca) was defined to quantify the cavitation degree. The predicted flow characteristics at the sharper edge of 0 degree and at 180 degree showed comparable trends as the experimental data. A higher Ca was observed upstream of the nozzle but it became lower at the exit
