This paper reports the results of mathematical modelling and simulation of two-phase flow near the outlet of six different industrial fan-spray atomizers under different operating conditions.
The Finite Volume Method, implemented in the commercial code, Fluent V.6.2, has been used to solve the mathematical model numerically, whilst the Volume of Fluid (VOF) approach has been employed to track the interface between liquid and gas. Surface tension effects have been included using the Continuum Surface Force method (CSF).
Results from simulation have been validated with experimental data and compared with those from previous works. Interesting conclusions about sheet thickness, velocity and vorticity of the flow have been obtained; some of them differ from hypotheses assumed in previous works. These conclusions may reflect the way in which break-up models are used to obtain drop size and break-up length.
