Nanotechnologies are increasingly used in various industries. The risks associated with nanoparticles are currently not well-known and then need to be further studied. Among the different possible hazardous scenarios with nanoparticles, the massive jet release seems to have received very little attention. Beside experimental approach, Computational Fluid Dynamics (CFD) tool constitutes an interesting approach to evaluate source term of a jet release. However, specific properties related to nanoparticles introduce new challenges in the modelling of such phenomenon compared to classical jet with particles. In that context, a new modelling framework has to be defined. In this paper, current qualitative and quantitative modelling available approaches are reviewed for jet release of nanoparticles and their relevance are discussed.
