o Improve profile performance based on a blade to blade streamline method
o Assess mechanical integrity (mean stresses, peak stresses and frequencies) based on integrated lean methods
* You stay in continuous exchange and interface to the Mechanical-, the Design- and the thermodynamic-department
* Apply 3D-CFD methods (ANSYS-CFX, Cadence-Numeca) to assess the multistage turbine performance characteristic and provide input for cycle performance prediction
* For the diffusor and exhaust at the exit of the low pressure turbine you:
o Generate aerodynamic diffuser designs
o Generate CFD meshes (ICEM, AUTOGRID, ANSYS-Mesh) for complex blade (shrouds, mid span connectors) and full exhaust geometries
o Run 3D RANS CFD to predict the exhaust recovery characteristic
* You are responsible for the technical quality of your work
* Continuously develop your own technical expertise.
* You may be asked to act as a reviewer (e.g. at a design, risk or project review) in your area of expertise
