If you aspire to deepen your expertise in experimental fluid dynamics and make a tangible impact on society, the PhD positions in Experimental Investigation of Inertial Dense Suspensions at TU Delft may be the perfect next step for your academic journey.Inertial Dense Suspensions (IDeS) are a cornerstone of both natural phenomena and industrial processes, appearing in contexts as diverse as blood circulation, waste management, additive manufacturing, and energy storage. Despite their prevalence, these flows remain poorly understood, hindering our ability to predict and control them with accuracy. This knowledge gap has significant implications: for instance, current models can misestimate the pressure drop in suspension pipe flows by up to 40%, complicating the design and operation of critical systems. The challenge arises because these flows do not fit neatly into traditional categories of laminar or turbulent regimes, instead occupying a complex middle ground characterized by unique inertial phenomena.As part of the ERC Advanced Grant project IDeS, TU Delft is seeking two highly motivated PhD candidates to join a dynamic research team dedicated to advancing our understanding of densely-laden pipe flows. The successful candidates will contribute to experimental investigations that push the boundaries of current knowledge, utilizing state-of-the-art measurement techniques and analytical tools.

The focus of this research is on the experimental investigation of inertial dense suspensions—complex multiphase flows where suspended particles significantly influence fluid behavior. These suspensions defy conventional fluid dynamics paradigms, exhibiting phenomena such as particle-induced fluctuations, gradual transitions to turbulence, and shear-induced migration. Understanding these mechanisms is vital for improving the design and efficiency of systems across multiple industries, from medical devices to energy infrastructure. The project’s outcomes will not only advance fundamental science but also enable the development of more reliable predictive models, facilitating innovation and sustainability in key sectors.
Project Details
The two available PhD positions, funded by the ERC Advanced Grant project IDeS, offer distinct but complementary research trajectories:– PhD 1 will employ advanced optical techniques, such as volumetric flow measurement (e.g., Lagrangian particle tracking or tomo-PIV), to quantify near-wall behavior and model particle-induced fluctuations. This work includes investigating how these fluctuations interact with the onset of turbulence.– PhD 2 will focus on ultrasound imaging velocimetry combined with shadowgraphy to study shear-induced migration of particles, developing models that account for variables such as volume fraction, particle size, Reynolds number, and density ratio.Both positions are based in the Process & Energy (P&E) department within TU Delft’s Mechanical Engineering faculty, which boasts a comprehensive suite of flow facilities and advanced measurement modalities, including MRI and ultrasound systems dedicated to multiphase research. Responsibilities include conducting experimental research, publishing in peer-reviewed journals, presenting at international conferences, and mentoring undergraduate and master’s students. Professional development is supported through a range of technical and non-technical courses.
