PhD on NMR and CT imaging phase change materials in heat storages

• Do you want to unravel the crystallization of phase change materials in heat storage devices?
• Do you like to work with advanced imaging techniques like CT and MRI?
• Do you want to understand the relation between crystallization processes and the power output of a heat storage?
• Are you inspired by thermal storage solutions to boost the energy transition?

Information
In your project, you will contribute to compact short term (daily) heat storage based phase change materials (PCM), by in-situ investigation of crystallization/melting processes in heat storage devices. Your research questions will be: Where does crystallization happens in a device and how does this impact power output? How can Magnetic Resonance Imaging (MRI) and X-ray Computed Tomography (CT) be used to visualize and analyze in-situ processes (e.g. phase transitions, flow dynamics, stratification) inside thermal storages containing PCMs? How can we describe via validated multi-physics simulation models; heat transfer, flow behavior, and phase changes?

Your task is to investigate localized flow and crystallization processes of PCMs in devices under different conditions with advanced 3D imaging tools like CT and NMR imaging, and to couple this with performance characteristics of the device like power, cyclability, partial discharge/charge and stratification. You will make use of unique infrastructure at the DarcyLab at Eindhoven University of Technology, where advanced imaging techniques such as Magnetic Resonance Imaging (MRI) and X-ray Computed Tomography (CT) enable in-situ visualization of flow and phase change processes. Your task will also be translating the experimental results in physical models describing the observed processes.

The PhD work embedded in the Topsector program Urban Energy and aims to contribute to local grid balancing, and increased efficiency of renewable energy generation.

Working location
The work will be performed in the group Transport in Permeable Media (TPM) in the Applied Physics department of the Eindhoven University of Technology.
