Project details

Swirling flows are commonly present in flow separation devices used for air and water filtration (e.g. automotive particulate matter filters, cyclone separators, microfiltration and water treatment devices). In some cases, swirl is the intrinsic part of the system, in others it is introduced to improve system filtration efficiency, while reducing fouling and other undesirable phenomena. Swirl also increases the residence time within the system.

However, very high swirl levels result in high flow losses and flow non-uniformities, caused by formation of central recirculation zone and time-dependent instabilities.

Understanding complex characteristics of swirling flows is crucial for design of efficient filtration systems, and this project is focused on development of novel experimental and numerical techniques for swirling flows in particle filtration applications. Thus, the aim of this project is experimental and numerical investigation of swirling flows in filtration applications.

The project will involve design of bespoke experimental flow rigs, pressure, temperature and flow measurements (Hot Wire Anemometry and Particle Image Velocimetry) in different simplified filtration flow configurations, and development of numerical methods for flow and particle transport modelling.
