Beyond the implementation of water physics in QuickSim, further development of the injection model was accomplished. The improvements of the injection model were realized by coupling optical measurements performed in a constant volume chamber and by the setting of a new methodology to calibrate the simulations with a repeatable analysis of both experimental and numerical results. Axial and radial penetration curves, injection tip velocity, as well as jet angles, were measured and evaluated. The injection model calibration realized through these data, enhance the simulations’ reliability.
