CFD analysis of sedimentation phenomena

Separation of suspended solids is one of the most important operations in a wastewater treatment plant (e.g. clarifiers). The range in solid sizes and their topology, usually found in wastewater, has led to a diverse set of separation approaches, which, as a consequence, also leeds to a diverse set of simulation methods when using CFD to tackle this subject (Wicklein et al, 2016). The basic distinction between methods lies on how the suspended elements are considered: either as a continuum (Eulerian approach) or as a discrete field (Lagrangian approach).

CFD modeling and optimization of a cooling pond

Phosphate fertilizer plants are installations constantly evolving which make their design a challenging task. Phosphogypsum, a by-product of the manufacture of phosphoric acid, is piled up, forming stacks which may eventually alter the process efficiency as they encroach on process cooling ponds and locally modify the airflow fields. The increase of computational power and its easier access allow to fully consider the use of CFD within tight-schedule industrial projects, even the ones involving large-scale geometry.
