THE DISPERSAL BEHAVIOUR OF ENGINEERED NANOMATERIALS (ENMs) USING CFD APPROACH

Use of powders in the nm-range such as ENM in the industrial settings has increased due to the unique properties exhibited by these materials. This increase in demand for nanopowders in industry lead to more associated hazard as ENM has its own potential hazard that may harm people and environment. However, very few known and aware about the explosion risk of ENM. Therefore, this project will focus on developing a dispersion model to study the dispersion behaviour of ENM that lead to the explosion. The project use ANSYS FLUENT CFD simulation software to develop the model. In this project, the time-averaged Navier-Stokes equation was used since it is most reliable in order to study on the fluid flow and the simulation was based on an Eulerian-Lagrange approach to study the behaviour of dispersion of ENM particles inside a 20L spherical explosion chamber.
