Information about the project
You are hereby invited to apply for a PhD student position in the project correlation and physics based prediction of noise and CO2 emission scenarios for aircraft and propulsion systems. The project involves using and developing a multidisciplinary propulsion and aircraft simulation platform developed at Chalmers. Ground noise measurement data and flight management system data from operational aircraft will be made available to the project. The data will be used to support the optimization and scenario studies.

At project start models for state-of-the-art aircraft and propulsion systems will be used to develop trade studies between CO2 emissions and noise. The modelling will then be refined through use of the ground noise measurements and by extending the aircraft trajectory analysis from 2D to 3D flight paths. A special case will be to look at how electrifcation influences noise emissions around airports.The work will be performed in collaboration with airlines and air service providers involved in the project.

The project is run as a collaborative effort between Chalmers and KTH as part of the centre for sustainable aviation. As a Ph.D. student you will establish a strong contact network not only with KTH researchers but through a number of EU-projects where the research group is already involved. This helps to build a case for a future academic career, alternatively it establishes contacts with a wide range of potential future employers in the aircraft engine industry. It is also the intention that, as part of the Ph.D. position, a 2-4 month research stay at an internationally well established university will be made.

On a societal level the research is expected to contribute to the reduction of noise from aircraft operation around airports. Long term exposure to high levels of aircraft noise is known to increases the risk of cardiovascular disease and has also shown to have a negative influence on childrens learning in schools. The project aims to find ways to reduce aircraft noise and still lower CO2 emissions, which in turn will reduce the climate impact from aircraft operation.

About the division
This PhD position will be a part of the division of Fluid Dynamics. Our research at the division covers turbulent flow (both compressible and incompressible), aero-acoustics and turbomachines. Our tools include both computations and experiments. In some research projects the smallest turbulent scales are studied whereas in others the function of a complete gas turbine is analyzed and modelled.

About the department
The Department of Mechanics and Maritime Sciences (M2) has a multidisciplinary research portfolio, exhibiting strong theoretical and experimental skills within seven research divisions in mechanical engineering and maritime sciences. We are able to implement unique combinations of physical and theoretical modelling, using in-house research facilities and through access to our partners’ infrastructures.

Major responsibilities
Your major responsibilities as a PhD student is to pursue your own doctoral studies. You are expected to develop your own scientific concepts and communicate the results of your research verbally and in writing, both in Swedish and in English. Your research will be supervised by well-reputed senior researchers and since the group has a strong position in aircraft propulsion you will be encouraged to collaborate with fellow students on publications and courses. The everyday work also means taking a number of doctoral courses, reviewing literature, designing research studies, interacting with industrial companies, collecting and analysing empirical data, and reporting research results.

The position generally also includes teaching on Chalmers' undergraduate level or performing other duties corresponding to up to 10 percent of working hours.

Position summary
Full-time temporary employment. The position is limited to a maximum of 4,5years.

Qualifications
To qualify as a PhD student, you must have a master's level degree in Mechanical Engineering, Aerospace Engineering, Engineering Physics, Engineering Chemistry with Physics or equivalent with special interest within relevant fields in fluid dynamics, turbomachinery and software development. The position requires oral and written communication skills in English. Swedish is not required, but you will be encouraged to learn Swedish during employment. Experience in programming (in particular Python), interdisciplinary cooperation, writing of scientific papers, hands-on experience of working propulsion and aircraft simulation codes are meritorious.

For this project we are looking at a motivated and analytic candidate, with a strive to produce quality work. A strong study result with a good background in modelling and simulation is expected. A background in turbomachinery, propulsion or aeronautics are meritorius. Likewise a strong and documented experience in developing system simulation models and tools is meritorius.

Chalmers continuously strives to be an attractive employer. Equality and diversity are substantial foundations in all activities at Chalmers.
