A calibration method for an evaporating impingement spray model was presented. First

spray penetration

SMD and mass distributions of vapor/liquid phases in sprays

which were impinged on the flat walls of a high temperature and high pressure bomb that could simulate the actual in cylinder ambient condition of a diesel engine

were measured using laser based approaches. Then a breakup model

a wall interaction model and a vaporization model were developed

verified and calibrated by the above measured parameters. Next

the prediction of spray under different conditions was made using these calibrated models and verified by the measured data

revealing the influences of main calibration parameters on evaporation characteristics

such as the effect of rebound Weber number on vaporization. Finally

the method was proposed to select the major calibration parameters for the evaporating impingement spray model.
