Postdoctoral Fellow

Experimental and Numerical Investigations of Pollutant Transport in a Model City

Your tasks

We are seeking a person to join our team and contribute to the research in the area of aerosol transport. Your responsibilities will include:

  • Characterizing and specifying the experimental set-up and particle transport test matrix
  • Designing mock-ups of scaled-down urban environments
  • Conducting experimental tests to cover relevant turbulence and particle size ranges
  • Analysing experimental results, including processing of Particle Image Velocimetry PIV data, and creating a benchmarking database for CFD code validation
  • Contributing to the development of a CFD particle transport model based on experimental results
  • Collaborating with the water and wind tunnel team at EMPA
  • Collaborating with scientists in the area of atmospheric chemistry to gather and prepare the necessary city-scale data
  • Collaborating with the computational fluid dynamics CFD modellers for modelling and validation of the transport of aerosols over urban environments
  • Publishing research results in relevant journals and conferences as well as and preparing technical reports
  • Bachelor’s and Master’s student supervision

Your profile

  • You have a PhD degree in Mechanical Engineering, Atmospheric Sciences or other related scientific field
  • You are highly motivated and skilled experimentalist with a solid background in fluid flow field characterization
  • You have practical experience in large-scale Particle Image Velocimetry PIV and data analysis, also a working knowledge in particle generation and characterization
  • You have good understanding and knowledge of CFD simulations, and ideally experience in the use of CFD codes
  • You are proficient in both spoken and written English
The main research work will be located at PSI, and the experimental work will be performed at EMPA institute; thus, you are willing to commute between PSI and EMPA institute.

We offer

Our institution is based on an interdisciplinary, innovative and dynamic collaboration. You will profit from a systematic training on the job, in addition to personal development possibilities and our pronounced vocational training culture.
