Comparison of numerical models for prediction of pressure-swirl atomizer internal flow
Original language description
Numerical prediction of discharge parameters allows to design a pressure-swirl atomizer in fast and cheap manner, yet it must provide reliable results for a wide range of geometries and operating regimes. Many authors used different numerical setups for similar cases and often concluded opposite suggestions on numerical setup. This paper compares 3D (three-dimensional) periodic numerical models used for estimation of the internal flow characteristics of a pressure-swirl atomizer. The computed results are compared with experimental data in terms of spray cone angle, discharge coefficient (CD), internal air-core dimensions, and velocity profiles. The internal air-core was visualized by high-speed camera with backlit illumination. Tested conditions covered wide range of the Reynolds numbers within the inlet ports, Re = 1000, 2000, 4000. The flow was treated as both steady and transient flow. The numerical solver used laminar and several turbulence models, represented by k-ε and k-ω models, Reynolds Stre
