Postdoc Simulation-based Material Analysis for Representative LIBS Technology

Join for smarter sampling strategies

Job description

Characterizing large volumes of heterogeneous granular materials presents a significant challenge, particularly for critical raw materials (CRMs) such as ores and industrial scrap. Material properties like particle size, shape, density, and composition can lead to segregation and inhomogeneous flow, complicating representative sampling and analysis. Material handling under harsh industrial conditions—dust, vibration, and temperature extremes—further increases the difficulty of accurate and representative material characterization.

Your work aims to improve the accuracy and reliability of CRM characterization under real-world industrial conditions by modelling the material behavior itself through Discrete Element Method (DEM) simulations. Insights from these simulations will inform strategies for representative sampling, including optimal locations for analytical measurements using LIBS (Laser-Induced Breakdown Spectroscopy). Validation on a simplified lab-scale system will be conducted to refine these strategies and fundamental understanding.

Your work will contribute to the circular economy by improving the identification and recovery of CRMs from secondary sources. The combination of DEM simulations with sensor measurements will advance simulation-informed engineering and the smart industry.

You will work within the Machines & Materials Interactions section of TU Delft that aims at designing the next generation of machines in the transportation domain, taking into account their interactions with cargo, materials and objects that they manipulate; interaction with environments; and interaction between machines in the logistic system. The research interests and expertise include advanced modelling and design optimization methods for machines development. We use both experimental testing approaches and computational modelling and closely collaborate with many national and international experts across companies and research/academic institutes.

• Holds a PhD degree in Mechanical Engineering, Chemical Engineering, Materials Science, Physics, or a related field
• Has demonstrable experience with Discrete Element Method in combination with experimental work
• Has excellent communication skills and demonstrates a collaborative mindset
• Preferably has experience as a Post Doctoral researcher
