| Research Abstract |
Numerical analysis method for the prediction of primary atomization under cryogenic conditions has been developed. The verification has been conducted through the comparison with corresponding experiment, which is fundamental atomization of liquid sheet. Thus, numerical analysis of atomization of liquid sheets and jets at coaxial type and impingement type injector has been able to be carried out. It was confirmed that gaseous velocity and recess is important factor for the primary atomization at coaxial type injector.
