Postdoc in Multi-Physic Modeling of High-Pressure Membrane for Renewable Energy Generation – DTU Chemical Engineering

Updated: 4 months ago

Mass transport processes in membrane-based systems are of great scientific and practical importance in a wide range of applications such as green energy and water technologies. These processes are affected by various factors of fluid dynamics, membrane module configurations, and material/structural characteristics. Specially in high-pressure membranes, enhancing solute mass transfer needs a detailed understanding of the interactions of complex fluid flow processes, multi-species transport and structural deformations under high-pressure loadings. 

This postdoc project will develop multi-physic modelling approaches and innovative numerical methods to describe material transport processes through high-pressure membranes. The position is part of a research project funded by the Innovation Fund Denmark to develop the next generation of high-pressure systems, energy recovery components and osmotic membranes for the production of sustainable energy. You will have the opportunity to deepen your modelling understanding and develop your theoretical skills in the field of high-pressure membrane for osmotic energy production. 

The postdoc will be part of the PROSYS research center at the Department of Chemical and Biochemical Engineering. Our research in the center has focus on process systems engineering including membrane-based systems design and development. The project is highly interactive and you will work together with both industrial and academic experts in the field.

Responsibilities and qualifications
The focus of this postdoc position is on development and implementation of fluid dynamic and fluid-structure interaction (FSI) models for membranes used in pressure retarded osmosis (PRO). More specifically, the candidate is expected to:

  • Design efficient numerical strategies to handle the nonlinear multi-physic problem of high-pressure PRO membrane flow 
  • Develop CFD-based detailed models to describe mass transfer and flow phenomena in PRO
  • Couple the fluid dynamic model with structural model to explore the fluid-structure interactions of the membrane module elements (porous layer, spacers, and supports etc)
  • Optimize the membrane module configuration based on the multi-physic model findings
  • To interact with the other partners of the project for experimental data analysis and design suggestions

As a formal qualification, you must hold a PhD degree or equivalent in chemical or mechanical engineering with the focus on fluid dynamic and FSI simulations. Furthermore, the ideal candidate should have hands-on experience from modelling membranes with help of CFD software tools such as Comsol or ANSYS Fluent (UDF programming).
