Numerical simulations of simplex pressure-swirl atomizers can aid their design process toward better atomization. This work aims at studying the two-phase flow at both the internal geometry and the first millimeters of the external domain of such ato

Publikováno v: International Journal of Multiphase Flow
International Journal of Multiphase Flow, Elsevier, 2019, ⟨10.1016/j.ijmultiphaseflow.2018.10.009⟩
Traditional Discrete Particle Methods (DPM) such as the Euler–Lagrange approaches for modeling atomization, even if widely used in technical literature, are not suitable in the near injector region. Indeed, the first step of atomization process is
