You will be responsible for reporting and communicating the results of your research to project stakeholders and to academic community.

Who we are looking for:

  • You have several years’ of experience in CFD (OpenFOAM, Ansys Fluent or similar) and multiphase fluid simulation.
  • You have solid and up-to-date knowledge in High-Performance Computing (HPC) and programming (OpenFOAM and/or Ansys Fluent).
  • You have experience in one or more of the following areas: Heating, Ventilation and Air Conditioning (HVAC) systems, ventilation design and design tools, air distribution principles and air filtration.
  • You have experience in experimental measurement techniques and the ability to design and build up setups to validate CFD and multiphase fluid simulation models. Profound experience in measurement and control software (e.g. LabView) is an asset.
  • You have excellent skills in academic publishing of the research results.
  • You have a doctoral or master´s degree in advanced energy solutions, buildings and built environment, thermal comfort or a related field connected closely to airborne contamination control.

As a person, we hope that you are:

Acting as a team member in a project environment requires flexibility, willingness to communicate and co-operate with customers and research partners.

Good communication skills in spoken and written English are necessary. Experience in project or customer work is an asset. The ability to apply theoretical understanding to create practical solutions will be highly appreciated.
