This work is devoted to the creation of the flagmanFoam software package developed on the basis of the OpenFOAM v2012 package. A solver has been developed to simulate icing in conditions of small droplet in-flow, with a characteristic droplet size of up to 40 microns, which corresponds to Appendix C of the Aviation Regulations AP-25. Computational models implemented in the solver are presented: the Euler-Euler approach is used to describe the dynamics of a gas-droplet flow, the Myers thermodynamic model is used to describe the growth of a liquid film and ice, the Coupled Level Set - VoF method is used to move the interface, to take into account the interaction between liquid and body, the immersed boundary method is used, the turbulent viscosity is calculated using the k-w SST turbulence model. The results of modeling on test problems and comparison with experimental data are presented.
