We are now looking for a student to take on the assignment
Investigation and Optimization of the cooling performance of a matrix cooling scheme
The assignment:
To meet the required lifetime of blades and vanes in the turbine hot gas path, different cooling techniques must be used to decrease the metal temperature. One of the more commonly used cooling techniques is the so called “Matrix Cooling” or “Vortex Cooling”. This method has the additional benefit of increasing the structural robustness of the component which makes it a favorite in many cooling designs within the gas turbine industry.


Flow visualization has shown that there is little flow mixing between the pressure and suction side channels, but these experiments have usually been performed for idealized geometries and without taking for example effects of rotation into account. Generally thermal modelling has been performed using a coupled flow network approach but nowadays CFD is also often used as a design tool.
In this work we want the student to help us to learn more about the flow in the matrix cooling system using a commercial CFD tool.
To understand the flow physics in the matrix better
To propose how to model the matrix using CFD to capture the heat transfer accurate enough
To investigate how different design parameters affect the heat transfer in the matrix

These investigations will then be used to improve the guideline how to model matrix cooling systems using CFD and to improve the methods in the in-house codes currently used to design and predict the metal temperature.


Your Profile:
- Student at MSc level with focus in mechanical engineering and flow physics
Have good knowledge about fluid dynamics, thermodynamics, heat transfer and CFD.
Is structured and can communicate well.
Who can find own ways and solutions to challenges
