Vielen Dank für Ihr Verständnis. 100%, Zurich, fixed-term The Energy and Process Systems Engineering (EPSE) Group at ETH Zürich is looking for a doctoral student working on the integrated design of process and refrigerant for industrial high-temperature heat pumps.

The position connects basic research with applied engineering, and focuses on developing more flexible and efficient high-temperature heat pumps.

The research of the EPSE group at ETH Zürich, headed by Prof. Dr. André Bardow, focuses on sustainability in energy and chemical process systems.

We develop methods to advance sustainable energy and chemical process systems from the molecular to the systems scale. In our work, we combine computer-aided molecular and process design to optimize molecules and processes simultaneously.

To holistically evaluate the environmental impacts of chemicals and energy systems, we develop predictive methods for Life Cycle Assessment.

Our technological focus currently lies in Power-to-X & sector coupling, sustainable carbon feedstock, and carbon capture, utilization & storage.

Project background High-temperature heat pumps are a key technology to decarbonize industrial heat generation. Replacing current fossil-based heating with industrial heat pumps can reduce carbon dioxide emissions by 80% in the short term and offers to reach carbon neutrality in the long term by using green electricity.

However, heat pumps have penetrated industry slowly so far. In particular, maximum temperature are currently limited to about 150 Â C, investment costs are higher, and efficiencies only moderate, hampering the adoption of heat pumps in industry.

Since existing industrial heat pumps evolved mainly from household applications, the potential for customization to industrial applications has not been exploited yet.

This project aims to overcome the challenges of industrial heat pumps by introducing refrigerants and process designs with temperature glide, e.

g., realized by refrigerant mixtures. Heat pumps with temperature glide can optimally meet the specific requirements of industrial applications, significantly increasing flexibility and efficiency.

To tailor high-efficient high-temperature heat pumps to industrial applications, we will combine modeling and experiments.

Refrigerants will be optimized for industrial applications by an integrated refrigerant and process design framework. An experimental high-temperature test stand and a heat pump breadboard system will be developed to enable validation and demonstration.

The modeling is mainly assigned to our group while our project partner will conduct the experimental research. Both groups will work in close collaboration to establish high-temperature heat pumps for industry.

Job description As part of the project team, you will focus on the modeling of the components and the overall. You will set up the integrated refrigerant and process design framework, which will be based on computer-aided molecular design (CAMD), a thermo-economic heat pump process model, and detailed component models.

You will benchmarking the novel technology and identify promising applications. You will collaborate with a further PhD candidate who will focus on the thermodynamic basics and develop models for property prediction.

Furthermore, you will be in close interaction with our project partner, who will conduct the experimental research. This connection offers you the opportunity to develop, advance, and validate your models on experimental results.

Using the design framework, you will identify optimal refrigerants for typical industrial applications, which will be tested in a heat pump test rig operated by our project partner.

During your PhD you will get a deep understanding of process modeling, computer-aided molecular design, and industrial high-temperature heat pumps.

We offer you a full-time position for the duration of your doctoral studies, starting upon agreement with the earliest starting of 01 April 2022 .

You will work in an interdisciplinary team of researchers with in-depth experience in process design, energy system optimization, and life cycle assessment.

As an integral part of your work, you will publish your results in peer-reviewed journals and present them at international conferences.

Your profile We are looking for a proactive and motivated candidate who meets the requirements for a doctoral program at ETH Zurich and has an excellent Master's or diploma degree in chemical engineering, mechanical engineering, process engineering, or energy science & technology from a recognized University.

You should have experience in process modeling, programming and optimization. You are highly motivated to learn and apply modern simulation and optimization techniques and work in a dynamic environment with other doctoral students and postdocs.

The ability to work independently and excellent communication skills in English (both written and spoken) complete your profile.
