摘要

An improved primary atomization model for the jet-in-crossflow (JICF) atomization has been suggested and incorporated into the solver SprayFoam of OpenFOAM. The assumption of replacing jets with blobs, the maximum growth rate of the Kelvin-Helmholtz (K-H) wave, and its corresponding wavelength in the WAVE model are inherited. The present model assumes that the blobs move uniformly in the jet direction and accelerate uniformly in the crossflow direction to simulate the jet trajectory. It considers the Rayleigh-Taylor (R-T) wave on the liquid surface and assumes that the growth rate determines the R-T wave and K-H wave competition. The frequency, position, and mass of liquid surface breakup, the velocity, and the size of stripping drops are given in detail. Results of the present model have been compared with the experimental data in other literature under varying momentum flux ratios, Mach number, and air Weber number. The agreement between calculated results and the measured value is generally good, and a quantitative assessment of the model performance has been conducted.
