In this paper the computational fluid dynamic (CFD) method was used to simulate two-phase flow within high pressure swirl injectors. The two-dimensional axisymmetric swirl Navier-Stokes equations coupled with the Volume-of-Fluid (VOF) method was employed for accounting the formation mechanism of the liquid film inside the swirl chamber and the orifice hole of the high pressure swirl injector. The VOF method was used to identify the liquid-gas interface developing inside the injector. Numerical simulations were carried out under 7MPa injection pressure with constant needle injector lift. The time-series analyses were carried out for flow inside injector in the transient state and steady state operation. Numerical results were compared for the steady state operation with experimental and empirical data that available in the literature. Good agreements were obtained for discharge coefficient   d C and cone angle   with experimental data.
