Research Associate

At the Institute of Jet Propulsion and Turbomachinery (IFAS) we are are seeking for a

Research Associate (M/F/d) in the field of

**Modeling and numerical simulations of sustainable**
**fuel combustion**

to join our team. The position is available at the earliest possible date in a temporary
employment for 3 years and with the possibilities of achieving a doctorate.

Climate change imposes a drastic reduction of greenhouse gas emissions and urges
for a rapid transition towards carbon-neutral technologies with the final aim to
minimize pollution and preserve life on the planet_. _A promising strategy, the power-to
- fuel-to-power concept, uses the excess of renewable energy to produce fuels as
chemical energy carriers. One option is represented by hydrogen carriers. They can
be produced from renewable energy sources to be then employed in gas turbines with
no CO2 emissions_._
Hydrogen carriers, pure or blended, cannot be used in today’s engines as drop-in
fuels for their remarkably complex combustion properties compared to hydrocarbons.
They have different reactivity, flame speeds, and flammability limits as well as may
promote different flame stabilization mechanisms.
Highly-resolved numerical simulations on supercomputers offer the unique opportunity
to achieve a comprehensive knowledge of different environmental-friendly fuels with
reduced costs and faster than in the past, supporting the development process of new
technologies.

**Main responsibility**:
The successful applicant is expected to carry out numerical simulations of laminar and
turbulent flames of pure and blended hydrogen carrier mixtures under various
operating conditions and develop reduced order combustion models for Large-Eddy
simulations. The open-source OpenFOAM software will be employed.

**Required Qualification**:
Applicants should have a degree (Master’s or equivalent) in aerospace engineering,
mechanical engineering, computational engineering, or equivalent. We are looking for
applicants with a very good degree, with strong ability to work in a team, creativity, and
good communication skills. Programming skills (preferably C++) are required. English
language skills complete your profile.

Knowledge and experience in the following areas are desirable:

Computational fluid dynamics

Fundamentals of combustion

OpenFOAM

Python

Experience with unix operating systems

**Our benefits: **

Pay in accordance with the collective agreement TV-L, pay grade 13,
depending on the assignment of tasks and fulfilment of personal requirements.

A special payment at the end of the year as well as a supplementary benefit in
the form of a company pension, comparable to a company pension in the
private sector.

Interesting and diverse tasks in a pleasant working atmosphere with a friendly
and motivated team that works closely together.

Part-time employment is generally possible.

The TU Braunschweig has a family-friendly university culture, awarded the
“Family-friendly university” audit since 2007.

A wide range of continuing education and company health care programmes as

well as a vibrant campus life in an international atmosphere.
