Three positions are available in the “OpaqueFlows” project, funded by an ERC Consolidator grant. This project unveils dense two-phase flows. These flows consist of a fluid containing suspended particles or droplets; examples include blood, milk, and slurries. While these flows are abundant in nature and industry, they are currently poorly understood and difficult to model. This is due to the fact that these flows are opaque, and current optical measurement techniques cannot see through them; very little experimental data is therefore available. In this project, four new imaging techniques that can see inside these flows are combined. When applied to a series of benchmark flows, they each provide a different view. Combining these views gives unprecedented insight into the interaction between fluid and particles. This will enable us to formulate and validate efficient models for engineering applications.
The PhD candidates will construct the three benchmark facilities (including fully-developed two-phase pipe flow, laminar pipe flow with relatively large particles, and a facility for mud-like fluids). The benchmark facilities will be studied using in-house techniques (such as ultrasound imaging velocimetry and tomographic PIV), but also at specialised facilities in the labs of partners within the project. The candidates are expected to actively collaborate with other team members to elucidate the fundamentals of the interaction between fluid and particles.
Daily supervision will be provided by Dr. C. Poelma. The Multiphase Systems section is housed in the Laboratory for Aero- and Hydrodynamics, which provides a state-of-the-art infrastructure (both experimental and numerical). Close collaboration is encouraged with the Fluid Mechanics section, housed in the same laboratory.
Requirements
Candidates must have an MSc in Mechanical or Aeronautical Engineering, Applied Physics or a related field. A successful candidate needs to have:
(1) a thorough knowledge of fluid mechanics (including multiphase flows). He/she should have a strong background in experimental techniques (e.g. HWA, LDA or PIV).
(2) a deep scientific curiosity and strong motivation to work in the field of multiphase flows.
(3) strong analytical skills and the ability to work independently as well as in a team.
(4) strong communication skills, an affinity for writing in scientific journals and giving presentations at scientific conferences, and a good command of English.
