[EN] Fire suppression modeling depends on accurate characterization of the atomization processes of fire sprinklers.
Numerical modeling, particularly the volume of fluid (VOF) method, has been applied to understanding the
atomization behavior of an idealized sprinkler geometry consisting of a 9.5 mm inner-diameter cylindrical nozzle
and a flat, 25.4 mm diameter disk with a liquid flow rate of 0.87 L/s. The simulations have been performed with an
OpenFOAM based VOF solver, using the isoAdvector scheme for interfacial reconstruction. The sheet breakup
distance and film thickness were calculated and compared with measurements from a previous study. A mesh
refinement study identified the sensitivities in the predicted quantities to mesh resolution. This study enables further
application of the model to simulation of the fully atomized spray.
