The current research intends to provide a starting point to effectively model aerosol heat transfer in a narrow, enclosed body. This research can lead to future modeling of nano fluids including their heat transfer characteristics and erosion effects on the walls of an enclosure. The model was developed using ICEM CFD for the mesh and FLUENT for the fluid flow modeling. Six different aspect ratio enclosures were developed to study the effects of varying aspect ratio. The natural convection of air was developed first to establish the appropriateness of the models being used. A mesh check was performed using one of the natural convection cases to ensure the mesh was appropriate. The forced convection of air was then developed. The velocity vector, isotherm, surface heat flux, and surface nusselt number were recorded for future comparison to models. The models for nanoparticle natural convection were then activated to ensure the distribution of particles was as expected. This research proved that nanoparticle tracking can be accomplished with a computer model instead of using the traditional volume ratio method. The effects of aspect ratio on the surface heat flux as well as surface nusselt number were recorded for both natural and forced convection of air. The development of the appropriate model for particle tracking is started and proven to be valid. The natural convection and forced convection of air has been solved for future comparison to natural and forced convection.
