Delft University of Technology Applied Sciences
Delft, (Zuid-Holland), 38 hours per week
Job description
The application of micro-fabrication techniques opens an entire new range of opportunities and challenges in chemical reactor technology. Whereas micro-reactor systems with dimensions in the 10 µm range can be routinely built, their application in large throughput processing is questionable. This project aims at the definition of optimal scales and windows of operation for micro- or milli-reactor systems with large throughputs that are typical for the production of bulk chemicals or food products. The project will be a collaborative effort between Delft University of Technology, Eindhoven University of Technology and Wageningen University.The PhD student in Delft will perform Computational Fluid Dynamics simulation studies of gas-liquid and liquid-liquid two-phase flows in the targeted reactor systems. These CFD studies aim at obtaining a proper understanding of the flow regimes, G/L and L/L mixing phenomena, gas and liquid hold-ups, interaction of the gas and liquid flows with the channel wall, residence time distribution and axial dispersion, and G/L and L/S mass transfer rates. These flow properties will be determined as a function of gas and liquid flow rates, gas and liquid properties, channel size and geometry, channel wall wettability and roughness, etc. Micro Particle Image Velocimetry experiments in cold-flow models, rendering instantaneous 2-D flow fields with a spatial resolution on the order of 10 microns, will be used to obtain detailed local information on the liquid flow pattern, which can be used to validate and improve the physical models underlying the CFD calculations.
Requirements
Required education/skills:University Graduate
The candidate that we are looking for has a strong interest in fundamental scientific research and an open eye for applications. She or he has either an MSc degree in Chemical Engineering with a strong interest in transport phenomena and fluid dynamics, or an MSc degree in a field such as Mechanical or Applied Physics, with a solid basis in fluid mechanics and transport phenomena and the willingness to learn about chemical processes. We seek candidates who ranked among the top 25% during their BSc and MSc studies. The candidate should be a good communicator and a team-player as well as motivated and able to work with a high degree of independence. Fluency in spoken and written English is a requirement.
