Numerical Simulation On Dilute Phase Pneumatic Transport, Ethan T. Doan

Electronic Thesis and Dissertation Repository

Pneumatic conveying is a technique that is widely used in many industrial mechanical and chemical applications. In the case of cement manufacturing pneumatic conveying is a large scale operation moving several kilograms of material per second which consumes electrical energy (operation of fans) and money (replacement of filters to remove particles from the air). At St Mary’s Cement the pneumatic conveying line was studied with a CFD model. The treatment of the secondary solid phase was done with the DPM formulation in ANSYS Fluent and turbulence was modelled with k-ω SST. It was found that simple geometric alterations to the …
