Master Thesis – CFD evaluation of Gas Turbine ventilation

Medium sized gas turbines (MGT) are delivered as pre-packaged, compact units where the ventilation system is a crucial part of the explosion protection concept. As part of the transition to a de-carbonized energy system, new carbon neutral fuels play an increasingly important role for our gas turbines.

Since these fuels sometimes have very different properties than natural gas, which is the traditional gas turbine fuel, CFD analysis has become a vital tool to verify the safety of our gas turbines and enable a carbon free power generation.

The scope of this master thesis is to evaluate the impact of different fuels and CFD boundary conditions on the explosion protection system (dilution ventilation with gas detection) of medium sized gas turbines to enable operation using future green fuels.

LET’S TALK ABOUT YOU

Your profile
* MSc student in mechanical engineering, engineering physics, physics or similar
* Have a keen curiosity about complex CFD analysis and solving practical problems through simulations
* Willingness to combine practical insights with simulations to increase the safety level of our gas turbines and help enable our transition to green, carbon free power generation.
* Experience with CFD analysis software Ansys/Fluent is good but not a requirement.

Your responsibilities
* Study the impact on different gas fuels on the gas turbine explosion protection system.
* Propose and document guidelines for evaluation of which different gas compositions that can be used with the existing systems and where separate analyses are required.
* Carry out comparative studies on how different boundary conditions affect gas clouds inside the GT enclosure.
* Study the impact of different enclosure geometries on the internal ventilation and gas clouds dispersion.

Your opportunities for personal growth
* Get the opportunity to work with a world leading green power company alongside specialists in many different areas from all around the globe, help us decarbonize our society and work for a cleaner and greener future.
* Develop your interpersonal skills by interacting with multiple engineering teams as you gather knowledge on the workings of a Gas Turbine.
* Opportunity to gain knowledge on CFD analysis of gas dispersion and ventilation.
* Risk mitigation of explosions in confined spaces.
