Master Thesis – Pump efficiency
Join us on our journey into the future #FutureMakers#Siemens
Be part of an open and dynamic workplace where professional and personal development is high on the agenda. By making sustainable energy solutions more cost effective, developing new technologies for the future's smart industry and electrifying passenger and freight transport, we make reality of our vision of a sustainable world.
We are now searching for a Master Thesis student to Siemens Industrial Turbomachinery AB in Finspång, Sweden. The Master Thesis project will result in a report from the results of the testing with 3D models of how the pump flow varies with different outlet pressures and fluid viscosities.
The challenge - Background / problem statement
The gas turbines use fuels for combustion and in the liquid fuel system for the SGT-600 – SGT-800 there is a frequency controlled high pressure pump. The pump is an internal gear pump commonly used in the hydraulic industry.
The flow through the pump is in the gas turbine governor represented by a linear function, pump speed versus fuel flow. This assumes that the pump has a constant efficiency, which is estimated. The efficiency of the pump is dependent of the outlet pressure from the pump, the viscosity of the pumped fluid (fluid temperature) and manufacturing tolerances in the pump among others.
The work is going to study the efficiencies of the 3 different pumps (same type of pump, only difference is size) theoretically and practically to see if the accuracy of the control of liquid fuel supplied to the gas turbine can be improved.
Topic – what will the degree project involve?
Deliverables – what is expected?
The degree project will result in a report from the results of the testing with 3D models of how the pump flow varies with different outlet pressures and fluid viscosities. Suitable software for displaying the results from the flow testing is Matlab, but not required since this could be done in other software programs as well.
The final report should include suggestions for improved flow accuracy through the pump to be used in the gas turbine control system.
Location
The student is to work in the Finspång for most of the time.
