The aim of this work is to improve the particle detection in the phase field of volume of fluid (VOF) simulations included in OpenFOAM. The reliable evaluation of the particle properties is a prerequisite for coupling the VOF method for the primary breakup with an Eulerian–Lagrangian simulation of the secondary breakup. Relevant changes to the code in order to achieve correct detection results are presented. As four numerical test cases demonstrate, the modified algorithm is capable of detecting particles and their size, position and velocity at an evaluation layer accurately.
