Simulation of Thermal Effects on the Flow Field in a Pilot-Scale Kiln Open
The flow field and coal combustion process in a pilot-scale iron ore pelletizing kiln is simulated using a computational fluid dynamics (CFD) model. The objective of the work is to investigate how the thermal effects from the flame affect …
The Effect of Reynolds Number on Jet in Asymmetric Co-Flows: A CFD Study Open
In rotary kilns in grate-kiln systems for iron ore pelletizing, a long and stable jet flame is needed to ensure a high quality of the pellets. The primary jet issuing from the nozzle interacts with two asymmetric co-flows creating a very c…
Modelling heat transfer during flow through a random packed bed of spheres Open
Heat transfer in a random packed bed of monosized iron ore pellets is modelled with both a discrete three-dimensional system of spheres and a continuous Computational Fluid Dynamics (CFD) model. Results show a good agreement between the tw…
