CFD-DEM SIMULATION OF PARTICLE-FLUID FLOWS
, 2014 ABSTRACT This work presents a numerical study of horizontal pneumatic conveying by the combined approach of computational fluid dynamics (CFD) and discrete element method (DEM), with special reference to the use of periodic boundary condition (PBC) for computational efficiency. A new iterative method is proposed to generally control the solid flow-rate

Global and Detailed Calculation of Tube Wall Temperature in a Process Furnace Steam Superheater
Chemie Ingenieur Technik, EarlyView.This study presents a comparison between an iterative global model and multiple approaches to a new non‐iterative model with the purpose of predicting tube wall temperature of a superheater. The results show that the non‐iterative method achieves sufficient accuracy while improving the prediction of local temperature distribution and better ...

CFD‐DEM modelling of blast furnace tapping
, 2017 The campaign length of a blast furnace is limited by the hearth inner lining lifetime. In order to maximize the campaign length and ensure a good draining of hot metal and slag, a good understanding of the flow in the hearth is essential. Challenges in modelling the flow involve several continuous phases (hot metal, slag and hot blast) as well as the ...

Transient thermal modelling of green anode cooling in the aluminium industry
The Canadian Journal of Chemical Engineering, EarlyView.Summary of the methodology. Abstract Anodes, which are used in electrolytic aluminium production, are made by mixing dry aggregate (petroleum coke, rejected anodes, and butts) with coal tar pitch, compacting the resulting paste (green anode), and baking (baked anode). After compaction, the anodes are cooled to maintain their structural integrity before
