Investigation of the flow with air-core in hydrocyclones

The present work focuses on the investigation of the flow with an air-core in hydrocyclones. These are used in many industrial sectors owing to their wide range of applications, including filtration, dewatering, concentrating or separation. Despite their popularity, there is still limited theoretical knowledge that could provide an explanation of the flow physics inside the hydrocyclone. Therefore, research on hydrocyclones is challenging, especially in areas directly related to the creation of the air-core. The numerical simulations in the present work were carried out based on a new numerical methodology. They present well-matched results compared with experimental data.
