What will be your role?

Researchers within the cluster Thermal Systems carry out projects on the efficient production and use of thermal energy for industrial processes. 

In our state-of-the-art Carnot and Mollier labs we develop and test thermal materials, components and  integrated systems from ~1 kW up to several MW scale. Clients such as end users in chemical industry, paper production, food processing and building materials, equipment manufacturers, system suppliers and process developers turn to us when specific, specialist knowledge is required, e.g. for the development of high temperature heat pumps, compact heat storage, advanced drying and dewatering technology and the implementation thereof.

As a researcher, your contribution will focus on developing thermal systems for industrial applications such as heat pumps, heat storage and the integration of those systems in (future) industrial processes e.g. cracking and drying. Your activities include development of models of thermal systems and industrial processes , execute experiments both in the lab and the field, use experimental data to validate the models, give input from model simulations to experiments and future experimental set ups including full scale industrial applications. 
The challenging projects are carried out in close cooperation with industry and other knowledge institutes, in both national and international consortia. You will regularly attend meetings with customers, e.g. to clarify a research question or present results.
You will be working on multiple projects simultaneously, with independence and autonomy being key in that regard.

Within a project team, you will be actively contributing your ideas and thoughts on possible solutions and carrying out research work, drawing on such things as analytical models, numerical models or experiments to this end. You will analyze and interpret results stemming from the data and your models in your research work and incorporate these results into a clear report. Best of all, your results will often feature in the recommendations issued to our clients to accelerate their transition towards CO2 neutrality!
