Prediction of multiphase flow and separation efficiency of industrial centrifuges by means of numerical simulation

Centrifugal separation of particles in a suspension is a prevalent challenge in various industries, including chemical processing, mining, food processing, and wastewater treatment. This method is crucial for tasks such as separating cream from whole milk to produce skimmed milk, isolating blood components, purifying beverages, and removing catalysts in multiphase reactors. Centrifuges, alongside sedimentation tanks and filters, are key devices for mechanical solid-liquid separation. While sedimentation relies on gravitational force due to density differences, centrifuges utilize centrifugal force. Filters operate based on differential pressure. The selection of the appropriate technique for a specific separation task depends on the mixture's properties, the separation's purpose—whether thickening solids or clarifying liquids—and the constraints of time and space. Advances in centrifugal technology have significantly enhanced the efficiency of separating very small particles, even at the nanometre scale, from complex multiphase flows, demonstrating its vital role in modern industrial processes.
