Abstract: | Many industrial applications involve particles transported by a carrier fluid flow with additional multi-physical effects such as electromagnetics. The simulation of such processes is computationally expensive especially because of the diverse dimensional and time scales involved. In this study, the time scale for the fluid flow to be stably simulated is shown to be up to 2 orders of magnitude higher than the time scale for a spherical particle to assume carrier flow velocity. A semi-transient solution methodology has been devised, utilizing a dual time stepping approach for the flow and particle simulations. In this methodology, first the flow field is simulated with the larger time step, saving the resultant fields at regular intervals serving as snap shots of the flow. Then between each snap shot, the flow is treated as steady state, facilitating the calculation of the particle trajectory based on the resultant forces. This approach is especially suitable for applications where the particle cloud density is low enough not to have a significant effect on the flow field warranting a one way coupling. The accuracy of the method is established by comparing key performance parameters such as coating transfer efficiency and the homogeneity of the coating obtained from a fully transient simulation. The saving potential in terms of computational resources is also quantified |
