In accordance with the results of previous experimental investigations, and starting from the formulation of conservation equations of mass, momentum and energy for the gas, the liquid and the interaction of them, including the normal stress action at the curved liquid stream head in the mixing chamber, the heat transfer and the work done by the shear stress at the parallel part of the interface of the two phases, a mathematical model for the gas-liquid two-phase flow in the Y-jet nozzle was established. Based on the theory of unsteady surface vibration and the theory of aerodynamic atomization in the literature, the two-stage breakup process of the liquid film from the exit of nozzle was modeled. Thus a complete mathematical modeling system for the performance prediction and design optimization of Y-jet nozzles has been formed.
