Master Thesis – Combustion simulations at Siemens Energy AB

LET’S TALK ABOUT YOU

Your profile
* A student of master’s degree in Physics, Computer science, Mechanical engineering or similar
* Interested in gas turbines, combustion and numerical simulations
* Willing to learn and try out new methods based on Computational Fluid Dynamics using Star-CCM+
* Previous experience with CFD and acoustic programs, programming skills and/or measurements is an advantage.
 

Your responsibilitites

* The topic of the master thesis is an investigation to further increase our fuel flexibility capability to further expand the usage of green fuels. The most challenging green fuel for dry low emission combustion is hydrogen and hydrogen enriched fuels due to its high reactivity moving the flame upstream causing risk of excessive heat load on the burner. The goal of this project is to study the performance of numerical simulations of various gas compositions and evaluate the results to already performed combustion tests.

* You will study the complexity of the interaction of air and fuel and you will learn to establish the following processes and validate those according to Siemens Energy Guideline:
+ Distribution of the mass flows, total pressures and energy fluxes.
+ Assessment of the temperature of chemical equilibrium in the reacting flow (flame temperature) with respect to local air to fuel ratios, enthalpy of air and fuel composition.

* In the development process Computational Fluid Dynamics (CFD), acoustic simulations, water tests, atmospheric and high-pressure combustion tests, and gas turbine engine tests will be used.
 

Your opportunities for personal growth:
* Increase your experience and knowledge in CFD calculations in Star-CCM+ and/or acoustic simulations, data post processing and verification of the results as compared to measurement data.
* Contribute to the mission on running on green fuels in the energy sector.
